Abstract:
Background: The ovaries frequently are the site for various primary tumors. Correct intraoperative diagnosis is crucial. The application of imprint cytology is very useful where frozen section facility is not available. The present study is a comparison of imprint cytology and frozen section during intraoperative consultation for various types of benign and malignant ovarian neoplasms in different age groups.Methods: Seventy-six cases of ovarian tumors were examined using both imprint cytology and frozen section and evaluated, taking histopathological report as gold standard. The histopathological diagnoses consisted of benign (54), borderline (9), and malignant (13). The malignant tumors consisted of various types including serous carcinoma, mucinous carcinoma, endometrioid carcinoma, clear cell carcinoma and carcinoid.Results: All 54 benign cases were accurately diagnosed as benign by imprint cytology. With frozen section 53 cases were correctly diagnosed as benign but one case was over diagnosed as borderline. Among 13 malignant cases 11 (84.6%) were correctly diagnosed with both techniques. Borderline tumors were not able to be diagnosed with imprint smear, 3 out of 9 cases were correctly diagnosed with frozen section.Conclusion: When compared with frozen section, imprint cytology is a simple, inexpensive and useful diagnostic tool in intraoperative diagnosis of benign and malignant ovarian tumors. Imprint smear is not useful in borderline tumors where only frozen section is useful. Imprint cytology can be used as an adjunct to frozen section for better diagnosis.

Abstract:
Rat estrous cycle determination or vaginal smear staining is paramount for studies related to endocrinology and reproduction; in the present study; we have reported a simple and rapid method for estrous cycle determination in rats using crystal violet. With this technique, the identification of stages can be done even on the next day. Hormonal variation in blood and histomorphological changes in ovaries at different stages of the estrous cycle were studied in female Wistar rats, which can be used to determine the hormone levels in works related to hormonal drugs, further ovarian morphology can be used to study changes in ovaries during the estrous cycle. This study aims to report a rapid and simple method for vaginal cytology using crystal violet and to report normal hormonal levels and histomorphology of ovaries in various phases of the estrous cycle.

Abstract:
Objective: To report the case of ovarian clear cell carcinoma with involvement of both ovaries and metastatic to ascitic fluid and the label mass in the bladderMethod: Case Report Case: A 51 years old female presented with enlarging abdominal with gradual pain. The result of transabdominal sonography were multiple cysts with solid mass, suspected solid cystic ovarian neoplasm and ascites. The patient prepared for laparotomy; optimal debulking surgery, mass resection from bladder. Cytology examination was performed from ascitic fluid and it was confirmed by histopathology examination.Result: Microscopic features on cytology examination of ascitic fluid smear was suggest carcinoma. Histological examination was confirmed the diagnosis and the result was ovarian clear cell carcinoma. Discussion: Ovarian clear cell carcinoma is a rare subtype of epithelial ovarian cancer and comprises about 5-10% of ovarian carcinomas. Clear cell carcinoma tends to occur in the fifth to seventh decades. Cytology examination showed the cellular smear consists of groups of epithelial cells with large nucleus, hyperchromatic, pale-staining, vacuolated cytoplasm. There is also eosinophilic, extracellular substance. The presence of a tumor in ascitic fluid and the label mass in the bladder can categorize become IIB. This determined based on the FIGO’s ovarian tumor staging system.Keywords: ovarian clear cell carcinoma; ascitic fluid.

Abstract:
Background: Cytology is a useful adjunct to frozen section for rapid diagnosis of neoplastic pathology. However frozen section facility is available in limited centres. Therefore, we undertook this study to find out role of scrape cytology for diagnosis of ovarian masses.Methods: It is an observational study done in a medical college. One hundred ovarian masses were collected for a period of eighteen months. Cut surface of ovarian masses were scraped with edge of a glass slide. Smears were prepared and stained with H and E stain, examined and a presumptive diagnosis was given. The verification of cytological diagnosis was done by histopathological report. All the data were recorded, tabulated and analyzed with the help of standard statistical methods using Microsoft XL.Results: A total of hundred cases were studied. Left ovary was involved in 38 cases, right ovary in 52 cases and bilateral ovaries in 10 cases. Malignant cases mostly yielded hyper cellular smear. On Chi square test, it was significant with value of less than .001. The overall sensitivity and specificity of scrape cytology in diagnosing ovarian neoplasm, considering HPE as gold standard, are 98% and 78% respectively. In Dysgerminoma, Papillary adenocarcinoma, Mucinous Cystadenoma, Benign cystic teratoma, Granulomatous lesion of ovary, Lymphoma and Mucinous adenocarcinoma, scrape diagnosis corroborated with the histological diagnosis. Notable discrepancy was seen in cases of Endometrioid carcinoma.Conclusions: Scrape cytology can serve as a powerful tool for early diagnosis of ovarian masses in close cooperation of the clinician, radiologist and pathologist. It has a potential for widespread use as knowledge and experience of interpreting cytopathologists increase.

Abstract:
Objectives: Peritoneal fluid cytology is done routinely in cases with serous carcinoma of ovary. However, morphologic features of borderline serous tumors (BSTs) of ovary in ascitic fluid have been rarely described. The aim of our study was to evaluate the morphologic features of BST with and without ascitic fluid involvement (BST+ and BST-, respectively) and compare with those of serous carcinomas, both in conventional and liquid-based cytology (LBC) smears. Material and Methods: Out of 30 BST cases reported in 3 years, seven cases had BST+. We compared the cytomorphology of seven cases of BST+, seven cases of BST-, and seven cases of serous adenocarcinoma with positive ascitic fluid cytology. Both conventional and LBC smears were studied in all cases and compared. Histopathology of omentum in these cases was also studied. Results: Most cases with BST+ had regular papillary fragment borders with nuclei showing mild-to-moderate pleomorphism, fine nuclear chromatin with small nucleoli as compared with serous carcinomas all of which had irregular borders with moderate-to-severe nuclear pleomorphism, coarse chromatin, and macronucleoli. Conclusion: A combination of cytoarchitectural and nuclear features can help in suspecting BST in ascitic fluid. Ascitic fluid cytology together with tissue histology can increase the rate of the detection of peritoneal implants.

Abstract:
Lymphoma of the female genital tract is a rare condition. Involvement of the ovary by non- Hodgkin lymphoma (NHL) is usually secondary to systemic disease and primary ovarian lymphomas are unusual. In most cases, the diagnosis is not suspected initially and is confirmed only after detailed histopathological evaluation. We describe two cases of primary ovarian NHL which were diagnosed on fine needle aspiration cytology (FNAC). One of the patients was a 40 years old female who presented with abdominal distension and lump. She was found to have bilateral adnexal masses on ultrasound and computed tomography (CT) scan. A USG guided fine needle aspiration of the ovarian masses was performed, following which a diagnosis of primary ovarian diffuse large B-cell lymphoma was established. The second patient was a 14 years old female who presented with pelvic lump, which was lobulated and mildly enhancing on contrast enhanced CT. A diagnosis of high grade NHL of ovaries was made on cytology. Subsequently, the lymphoma was characterized as Burkitt's on histopathological examination. Both the patients were started on R-CHOP chemotherapy regimen. FNAC serves as an extremely useful minimally invasive procedure for the diagnosis of ovarian lymphomas and early institution of appropriate chemotherapeutic regimens.

Abstract:
Abstract The experiment was conducted on 30 Holstein-Friesian cows: 10 cows in the follicular phase of the cycle and in the luteal phase 10 d later, 10 cows with follicular cysts, and 10 with luteal cysts. The presence of the ovarian structures was confirmed by ultrasonography. Serum levels of progesterone and 17β-oestradiol were tested with ELISA. Samples for cytological examination were collected from the uterus of all cows using a cytological brush. Following staining, the smears were evaluated in terms of quality and percentages of endometrial cells. In the follicular phase of the oestrous cycle, cells of type A - superficial cells (64.6 ± 4.48) were proportionally the largest group of cells. Cells of type C - basal cells (19.8 ± 2.75) were also present. In the luteal phase, the highest percentage of cells was of type B - intermediate cells (76.9 ± 4.26). When follicular cysts were present on the ovaries, the cytology resembled the follicular phase of the cycle, but with many younger type C cells (33.1 ± 4.11). In the case of luteal cysts on the ovaries, the cytology was similar to that of the luteal phase of the cycle, however with a lower percentage of type B cells (58.1 ± 5.71), and a slightly higher percentage of the other types. The differences in the cytological image of the uterus when different ovarian structures are present, depend on the hormonal activity of those structures. Due to the lack of literature data, the results of the study are important as a model, and may substantially facilitate identification of phases of the oestrus cycle, or the pathologies described, as well as indicate the current status of the endometrium

Abstract:
Dysgerminoma of the ovary is a rare malignancy. It is common in dysegenetic ovaries. The prognosis is excellent if treated properly. This is a case report of a girl with agenesis of the uterus, streak ovary and dysgerminoma. Her external genitalia seemed normal. Ultrasonography indicated uterine agenesis and showed a solid mass on right gonad. The left gonad was streak ovary. There was minimal ascites and cytology was positive for malignant cell. Tumor markers were normal. Bilateral gonadectomy with removal of the tumor was performed. She received chemotherapy and was disease free at 2-year follow up. The combination of an ovarian dysgerminoma with uterine agenesis and streak ovary is a rare finding. Ovarian dysgerminoma is chemosensitive and potentially curable even when in advanced stage.

Abstract:
Follicular growth in bitches is usually detected indirectly through behaviour observation, vaginal smears, and hormonal assay in blood. Although real-time ultrasonography can reveal the development of canine ovarian follicles, no method has been established to determine or predict ovulation accurately. Moreover, the location and small size of the ovaries make imaging technically difficult. This study was conducted to investigate follicular waves of canine ovaries stimulated by hormone treatment, in which ovaries had been clamped at a subcutaneous site. Bilateral malacotomy of 3 bitches (4 years of age) at the anestrous (2 bitches) and proestrous (1 bitch) stages of the oestrous cycle was performed using a ventral flank abdominal approach with routine techniques and materials. Each ovary that maintained blood circulation from the suspensory ligament was clamped at a subcutaneous site through muscles of the abdomen. Oestrus was induced using subcutaneous administration of 500 IU of eCG and 1000 IU of hCG (eCG/hCG). Each bitch was given 1000 IU of hCG at 11 days after eCG/hCG administration. Examinations with ovarian ultrasonography using a 7.5-MHz sector transducer, vaginal cytology, and serum progesterone assay were performed daily until 20 days after eCG/hCG administration, and every 10 days thereafter from 20 days to 60 days. Serosanguineous vaginal discharges and vaginal cytology of 2 of the bitches were observed. Follicular growth (>1.1 mm in diameter) was observed in all bitches after eCG/hCG administration. The appearance of new follicular growth was observed on 2 days, 6 days, and 8 days after eCG/hCG administration. The mean diameter of follicles reached 4.3 to 5.5 mm, and the maximum numbers of follicles in bitches were 11 to 16. However, all follicles regressed, irrespective of hCG administration. Elevation in progesterone levels (>2 ng mL–1) after eCG/hCG administration was observed from 2 days to 12 days after eCG/hCG administration. No correlation was found between follicular development, progesterone profiles, and vaginal smear characteristics. Follicular growth clamped at the subcutaneous site can be monitored easily using ultrasound without an experienced operator. Moreover, ultrasonography proved that hormonal stimulation can induce follicular growth, but the day of appearance of new follicles varied.

Abstract:
Ovaries maintain and produce functional female gametes, oocytes, for fertilisation. Oocytes develop inside cellular assemblies, the ovarian follicles, before birth and can reside there for up to 50 years in the human. Despite recent inroads, the precise mechanisms of initial follicle recruitment and growth remain unclear. Although the pituitary gonadotrophins play a role in this developmental process, locally produced factors have been implicated strongly in initiation of follicle growth. It is known that fibroblast growth factor 2 (FGF2) is a powerful mitogen for follicular granulosa cells in culture and initial studies undertaken in this project were successful in detecting FGF2 gene expression in ovarian biopsies from fertile healthy women. To further elucidate which cells were expressing FGF2, laser microdissection was employed to isolate differentially staged follicle populations. Real-time RT-PCR was used to quantify mRNA in relation to follicle development. Decreasing levels of FGF2 expression were detected as follicles developed. Non-radioactive in situ hybridisation confirmed FGF2 mRNA localisation in granulosa cells of preantral follicles. FGF2 protein localisation was assessed with immunohistochemistry; two primary antibodies raised against different fragments of human FGF2 were used. Both antibodies detected FGF2 in the oocyte cytoplasm of putative non-growing follicles, whereas only one of the antibodies showed additional reactivity to the basement membrane region of these same follicles. These results suggest different isoforms of FGF2 may localise specifically to different cellular sites. Follicle stimulating hormone receptor (FSHR) gene expression was also investigated in follicles using laser microdissection, real-time RT-PCR and in situ hybridisation. FSHR mRNA was detected in all follicle populations, including the smallest putative non-growing follicles. Disparity to other published works was attributed to the position of primer annealing, and thus the ability to detect alternatively spliced transcripts. In conclusion, the work presented here provides evidence that FGF2 and FSHR are present in small follicles and that their actions may be stimulatory or inhibitory to initial follicle recruitment.

Abstract:
Abstract Malignant tissue growth induces marked biochemical and structural changes in the extracellular matrix of the tumour and its surrounding tissues. In the present study, we evaluated the prognostic value of the serum concentration of the markers of synthesis of type I collagen (PICP, PINP) and type III collagen (PIIINP) as well as the marker of type I collagen degradation (ICTP) and compared them with the conventional indicators of prognosis (clinical stage, grade of differentiation, histological subtype, residual tumour load and the age of the patient). The prognostic value of peritoneal cytological findings at operation was an additional object in our studies. High preoperative serum ICTP (>5.6μg/L) and PIIINP (>3.2μg/L) concentrations and a low PICP:PINP ratio (>2) correlated with poor prognosis in ovarian carcinoma in univariate analysis and in multivariate analysis when each variable was analyzed separately with the conventional factors. However, ICTP concentration was the only prognostic variable in multivariate analysis including PIIINP, PINP, ICTP and CA125. When analyzed with conventional prognostic factors (clinical stage, grade, residual tumour, presence of ascites, histology), clinical stage and ICTP were independent indicators of prognosis. In addition, malignant cells in the peritoneal fluid aspirate at primary operation, grade and the age of the patient predicted poor prognosis in multivariate analysis. Postoperative serum ICTP concentration 9-months after the operation was the strongest prognostic factor as compared to the preoperative ICTP and CA125 values and clinical variables. These results indicate that serum collagen metabolites, especially ICTP, are indicators of prognosis in epithelial ovarian cancer. The present ICTP-test does not detect the degradation products of immature type I collagen, the dominating form in ovarian cancer tissue. Therefore, the excess ICTP in invasive ovarian cancer might originate through the degradation of trivalently matured collagens in non-malignant tissues surrounding the malignancy. ICTP may thus be an indicator of invasive properties of the tumor and its determination opens up new perspective to predict the clinical outcome of ovarian cancer.

Abstract:
L'ovogenèse chez la drosophile est un modèle pour l'étude au niveau génétique, cellulaire et moléculaire de différents processus impliqués au cours du développement des organismes multicellulaires tels que la prolifération, la différentiation, la morphogenèse, la migration et la mort cellulaires. Un follicule est composé d'un cyste de 16 cellules germinales, 15 cellules nourricières et un ovocyte, entouré par un épithélium composé de cellules somatiques qui adoptent différentes identités au cours de la maturation du follicule. Les cellules polaires présentes sous forme de paire à chaque extrémité du follicule, agissent comme centre organisateur de la différentiation des cellules folliculaires terminales en plusieurs populations. La formation des paires de cellules polaires se fait par un processus apoptotique qui élimine des cellules pré-polaires. J'ai étudié le rôle de deux modulateurs de la voie de signalisation Notch (N) : neuralized (neur) et D-mind bomb 1 (D-mib1) au cours de l'ovogenèse. J'ai montré que ces 2 gènes sont requis en lignée somatique pour la formation des follicules et des filaments interfolliculaires. Pour la formation du follicule, neur est requis dans les cellules somatiques des régions IIb-III des germaria pour l'aplatissement et le positionnement des cystes ainsi que pour la migration de cellules entre les cystes. L'étude et le rôle de neur m'a également permis de mettre en évidence un rôle de la voie de signalisation N dans la formation des paires de cellules polaires. Les résultats obtenus indiquent que les 2 cellules polaires sont sélectionnées par 2 mécanismes différents : une des cellules est sélectionnée grâce à l'activation de la voie N à un fort niveau qui la rend résistante à l'apoptose alors que l'autre cellule sélectionnée est réfractaire à l'activation de la voie N. De plus, j'ai montré que l'activation de la voie à un fort niveau dans une des cellules pré-polaires est dépendante de l'expression de neur et Dl au sein du groupe et cette activation est nécessaire pour l'élimination de cellules surnuméraires. Suite à cette étude nous avons proposé le modèle suivant : au sein du groupe de cellules pré-polaires, une 1ère cellule est sélectionnée par un mécanisme qui reste à identifier, une fois sélectionnée cette cellule induit l'activation de la voie N à un fort niveau dans une des cellules du groupe, cette dernière est alors résistante à l'apoptose, enfin l'activation de la voie N est nécessaire pour l'élimination de cellules pré-polaires non sélectionnées
Drosophila oogenesis is a model for studying cellular processes involved throughout the development of multicellular organism, such as proliferation, differentiation, morphogenesis, migration and apoptosis. An ovarian follicle is composed of a cyst of 16 germline cells, 15 nurse cells and one oocyte, surrounded by an epithelium composed of somatic cells. Within the follicular epithelium, the somatic cells adopt different identities during follicle maturation. A pair of cells located at each extremity of each follicle, called the polar cells, plays the role of an organizer to differentiate the terminal follicular cells into several populations. The formation of the polar cell pairs occurs via the elimination of some pre-polar cells through an apoptotic process. I have studied the role of 2 Notch signalling pathway modulators : neuralized (neur) and D-mind bomb 1 (D-mib1) during oogenesis. I have shown that these 2 genes are required for follicle formation and formation of the interfollicular filament. For follicle formation, neur is required in the somatic cells in the regions IIb and III of the germaria for the flattening and the positioning of the cysts and also for the migration of cells between adjacent cysts. The study of neur role allowed me to highlight a role of the Notch signalling pathway in the formation of the polar cell pairs. My results indicate that the two polar cells are selected by two different mechanisms : one of these cells is selected thanks to a high level of the Npathway activation, which makes it resistant to apoptosis, while the other selected cell is refractory to N pathway activation. Moreover, I have shown that the high level of N pathway in one pre-polar cell is dependent on the expression of neur and Dl within the pre-polar cell group and that this activation is required to eliminate the supernumerary cells. This study leads us to propose the following model : within the pre-polar cell group, the first polar cell is selected by an unidentified mechanism, once selected this cell induce a high level of N pathway activation in one cell of the group, this cell becomes resistant to apoptosis, and finally the activation of the N pathway is necessary to eliminate the pre-polar cells that are not selected

The aim of this research was to study the estrous cycle physiology of female collared peccaries bred in captivity at Semiarid. At the first experiment, the changes in hormonal status (estrogen and progesterone), vaginal cytology and ovarian ultrasonographic patterns were described and correlated in four mature females. It was monitored 1.5 estrous cycle per animals during 45 days evaluation, with an average duration of 21 ± 5.7 days, estrogen presented a peak value of 55,57 ± 20,47 pg/mL and during the luteal phase, the peak values for progesterone were 35.3 ± 4.4 ng/mL. The diameter of the ovarian follicles was 0.23 ± 0.1 cm during the moment of the estrogen peak and corpora lutea measured 0.36 ± 0.2 cm identified during the luteal phase, through ultrasound evaluation. No relations amongst the hormonal profiles and vaginal cytology were identified during any moment of the cycle (P > 0.05), it was suggested that the second method was not accurate for estrus monitoring in the above mentioned species. In the second experiment, we tested a protocol for synchronization of estrus in five female collared peccaries, using two doses of 0.8 mL (60 μg) of the prostaglandin analogue, cloprostenol, with an interval of nine days, performing alongside the dosage of estrogen to monitor the estrous cycle. The occurrence of estrogen peak was verified in all the animals after the second application at 9.2 ± 1.1 days, with an average of 28.05 ± 10.41 pg / ml estrogen, and the external signs of estrus, as opening vulvar, vaginal mucosa hyperemic and vaginal mucus were observed in four animals (80%). Therefore, it was proved the efficiency of the application of a prostaglandin analogue, cloprostenol, on estrus synchronization in this species.
O objetivo do presente trabalho foi estudar a fisiologia do ciclo estral de fêmeas de cateto mantidas em cativeiro no semi-árido brasileiro e desenvolver um protocolo para a sincronização de estro nesta espécie. Em um primeiro experimento, buscou-se descrever e correlacionar as alterações no perfil hormonal (estrógeno e progesterona), citologia vaginal e padrão ultra-sonográfico dos ovários durante o ciclo estral de quatro fêmeas de catetos. Foram observados 1,5 ciclo estral por animal em 45 dias de avaliação, com duração média de 21 ± 5,7 dias, o estrógeno apresentou um valor de pico de 55,57 ± 20,47 pg / mL e durante a fase lútea, os valores de pico de progesterona foram de 35,3 ± 4,4 ng / mL. O diâmetro dos folículos ovarianos foi de 0,23 ± 0,1 cm no momento do pico de estrógeno e corpos lúteos mediram 0,36 ± 0,2 cm, identificados durante a fase lútea, por imagem ultrassonográfica. Não foram observadas relações significativas entre o perfil hormonal e citologia vaginal, durante nenhum momento do ciclo estral (P > 0.05), sugerindo-se que o segundo método não é exato para o monitoramento do estro na espécie. No segundo experimento, foi testado um protocolo de sincronização de estro em cinco fêmeas de cateto, utilizando duas doses de 0,8 mL (60 μg) do análogo da prostaglandina, com intervalo de nove dias, realizando-se paralelamente dosagem de estrógeno para o acompanhamento do ciclo estral. Obtendo-se ocorrência de pico de estrógeno em todos os animais após a segunda aplicação em 9,2 ± 1,1 dias, com em média, 28,05 ± 10,41 pg/mL de estrógeno, sendo observados sinais externos de estro, como abertura vulvar, mucosa vaginal hiperêmica e presença de muco vaginal em quatro animais (80%). Os resultados sugerem que a aplicação do análogo da prostaglandina, cloprostenol, foi eficiente para sincronização de estro nesta espécie.

Abstract:
Introduction: Ovarian fibrothecomas represent an ovarian stromal neoplasm developing in a wide spectrum of clinical settings. These tumors have been described as rare ovarian neoplasm, accounting for about 4% of all ovarian tumors. We report a case whose clinical presentation was highly deceptive and was clinically and radiologically diagnosed as malignant ovarian tumor. Ascitic fluid cytology revealed absence of malignant cells. On histopathological examination, it was diagnosed as benign fibrothecoma with cystic changes. Postoperative follow-up for about six months was uneventful. Case: A 45 year old female presented to the gynae emergency with large abdominal lump of 20 weeks size with acute pain abdomen. She was admitted for initial management and thorough evaluation. Hematological and biochemical parameters were within normal limits. USG revealed a large multilocular, predominantly cystic lesion 20.9x9.6x11.4 cm in pelvis. CECT revealed ovarian cystadencarcinoma left ovary with locoregional mass effect, mild ascites and suspicious metastasis to internal iliac lymph nodes. Radiological and preoperative clinical diagnosis was malignant ovarian tumor. Panhysterectomy and omentectomy was performed. On gross examination, a well encapsulated, multinodular cystic tumor of left ovary about 17x14x7 cm was identified. Cut surface was mostly solid with few cystic areas. Uterus, cervix, right ovary and both tubes were unremarkable. On microscopic examination, multiple sections showed spindle shaped cells in storiform and palisading pattern. No mitotic activity was identified. On special staining, it was positive for vimentin, which is a characteristic feature of ovarian fibrothecoma. Conclusion: The accurate preoperative diagnosis of ovarian fibrothecoma with cystic changes could have prevented the extensive surgical intervention such as bilateral salpingo- oopherectomy with hysterectomy.

Abstract:
Introduction: Sertoli-Leydig cell tumor (SLCT) is a rare ovarian tumor, Constitute less than 0.5% of ovarian tumors. Most tumors are unilateral, confined to the ovaries. They are seen during the second and third decades of life. They are characterized by the presence of testicular structures that produce androgens. Patients have symptoms of virilization (depending on the quantity of androgen). Case Report: A 42-year-old woman presented Amenorrhea for 14 months. Change in her voice for 1 year and Excessive hair growth on her face, chest, and limbs for the last 2 months. She complained of vague abdominal discomfort. No history of anorexia, weight loss, increased libido. Her medical and family history was unremarkable. On examination - Hirsutism and clitoromegaly. Lump of size 10x8 cm palpable in left iliac fossa. Vaginal examination revealed a firm and mobile cystic mass in the right adnexa. An ultrasound examination of the pelvis showed a 17x 13x 9-cm heterogeneous solid cystic mass replacing the left ovary. The right ovary and the uterus were normal. CECT Scan Abdomen-Large heterogenous encapsulated solid soft tissue mass lesions containing areas of calcification arising from left ovary of size 17x13x10.6cm causing displacement of urinary bladder and surrounding bowel loops. Serum testosterone level -2 ng/mL (normal, 0.2–1.2 ng/mL); (DHEAS), CA 125, and alpha fetoprotein (AFP) -normal. On Laparotmy-Large mass of size 17 X 13 cm arising from left adnexa. Uterus and right ovary grossly normal. Total Abdominal hysterectomy, B/L Salpingo-opherectomy and infracolic omentectomy was done. Peritoneal washing were sent for cytologic examination for malignant cells. No liver metastasis. The post operative period was uneventful. Histopathology revealed- confirmed it be Sertoli Leydig cell tumor. 3month follow up – resolution of her virilization symptoms. No increase of her hirsutism. Repeat testosterone levels - within normal range. Conclusion: Only few cases of SLCT have been reported till date Prognosis depends on extent of disease, stage of disease, tumour differentiation, grade. The treatment should be individualized according to the location, state of spread and the patient’s condition.

Abstract:
Introduction: Over the last two decades there is a trend toward increasing incidence of ovarian cancer cases. CA-125 and some other tumor markers are known to have prognostic importance. Some cytokines have also been studied for their role in prognosis; IL-6 and VEGF are among them. It is hypothesized that these cytokines might affect the clinical progression of patients with ovarian cancer. Aim and Objectives: To measure and correlate the effect of levels of IL-6 and VEGF in ascitic fluid on presentation, treatment response and outcome in patients with epithelial carcinoma ovary and to determine whether levels of IL-6 significantly correlate with progression-free survival. Materials and Methods: Thirty patients with epithelial ovarian carcinoma and 15 patients who were undergoing hysterectomy for benign condition were recruited. Once patients found fit for study, they were taken up for primary debulking surgery. Ascitic fluid was collected and sent for measuring IL 6 and VEGF levels. Peritoneal washings taken from patients posted for total abdominal hysterectomy for benign pathology was used as control to achieve the values of IL-6 and VEGF in the study population. Patients were followed up for 1 year after surgery with ultrasound abdomen and pelvis and serum CA 125 levels. Results: Median value of IL-6 in ascetic fluid was 8563.18 pg/ml in EOC cases and 17 pg/ml in benign pathology group and of VEGF was 6090.35 pg/ml and 34.01 pg/ml, which were found to be significantly higher in cases compared to control group (p = 0.0001). Levels of VEGF was significantly higher in patients with positive ascitic fluid cytology (p = 0.009) and ascitic fluid volume >1L (p = 0.021). Correlation of VEGF and IL6 levels with other prognostic was not statistically significant. Levels of IL-6 and VEGF in ascitic fluid did not correlate statistically with survival time or with recurrence (p = 0.651). Conclusion: Levels of VEGF in ascitic fluid were found to correlate with ascitic fluid cytology and volume but not with FIGO stage, histological grade, histological type, tumor size, residual tumor, CA 125 levels, chemotherapy response, presentation and with overall outcome and survival time. None of the above mentioned prognostic factors were found to correlate with levels of IL-6 in ascitic fluid.

Abstract:
Aim: The study objectives were evaluation of clinicopathological characteristics, correlations between the preoperative and postoperative tumor assessment in early stage endometrial cancer. Materials and Methods: We conducted a prospective descriptive study of 30 cases of endometrial cancer stage 1 examined and treated at a tertiary care teaching institute between the years 2014-15. Results: The patients’ mean age at the time of diagnosis was 56.4 years. The mean parity was two. Postmenopausal bleeding with or without abnormal vaginal discharge was the most frequent symptom; it was present in 84.7% of patients. Co morbidities like hypertension and diabetes were seen in 65% of women. 6/30 patients had family history of some malignancy. All the patients underwent Type I extrafascial hysterectomy with bilateral salpingo oophorectomy, one case had Type I extrafascial hysterectomy with infracolic omentectomy. A total of 10.6% cases had lymph nodes metastasis and none of these patients had ovarian metastasis or positive peritoneal cytology. None of the patients with superficial myometrial invasion (MI) had lymph node metastasis. None of the cases showed positive peritoneal cytology. Staging upgraded fom 1a to 1b in 50% of subjects after final histopathological analysis. One patient who was operated as endometrial hyperplasia with atypia actually had endometrial adenocarcinoma in the postoperative specimen. Conclusions: There is a poor correlation between the preoperative and the postoperative tumor assessment.
