Resumen

Screening for systemic amyloidosis is typically carried out with abdominal fat aspirates with varying reported sensitivities. Fat aspirates are preferred for use in primary screening instead of organ biopsies as they are less invasive and thereby minimize the potential risk of complications. At Odense Amyloidosis Center, we performed a prospective study on whether the combined use of fat aspirate and tru-cut skin biopsy could increase the diagnostic sensitivity. Both fat aspirates and skin biopsies were screened with Congo Red staining, and positive biopsies were subsequently subtyped using immunoelectron microscopy and mass spectrometry. Seventy-six patients were included. In total, 24 patients had systemic amyloidosis (11 AL, 12 wtATTR, 1 AA), and 6 patients had localized amyloidosis. Combined fat aspirate and skin biopsy were Congo Red-positive in 15 patients (overall sensitivity (OS) 62.5%). Fat aspirates were positive in 14 patients (OS 58.3%), and the skin biopsy was positive in 5 patients (OS 20.8%). In only one patient did the skin biopsy add extra diagnostic information. The sensitivity differed between AL and ATTR amyloidosis—81.8% and 41.7%, respectively. Using skin biopsy as the only screening method is not recommended.

Resumen

Light chain amyloidosis (AL) causes irreversible multi-organ damage if not diagnosed early in the disease process. Fat pad biopsy is thought to be a highly sensitive screening test in systemic AL cases, especially if greater than three organs are involved. We present a case of a 64-year-old female who was admitted to the hospital with worsening heart and kidney failure, anasarca, increased free serum lambda light chains, and a negative fat pad biopsy for amyloidosis. Later, she developed asystole, bradycardia, severe hypotension, and respiratory distress. Because X-rays of her calvarium showed multiple osteolytic lesions, a bone marrow biopsy was planned to assess for multiple myeloma. Due to her non-reassuring vitals, the biopsy was not attempted, and she passed away several weeks later. Autopsy findings identified the cause of death as multiple system organ failure due to systemic AL. Through microscopic examination, pathologists found amyloid deposits in her heart, kidneys, rectum, thyroid, adrenals, bone marrow, liver, and spleen. Postmortem fat pad biopsy was negative; however, bone marrow biopsy demonstrated clusters of CD138-positive cells, confirming plasma cell dyscrasia. In cases with a negative fat pad biopsy, an additional superficial or involved organ biopsy should be pursued to establish a diagnosis of amyloidosis if strong clinical suspicion exists.

Resumen

Abstract Background It is not known whether acute tissue injury is associated with endoplasmic reticulum (ER) stress. Objective Our objective was to determine whether open, sc fat biopsies cause ER stress. Approach Five healthy subjects underwent three open sc fat biopsies. The first biopsy, taken from the lateral aspect of a thigh, was followed 4 h later by a second biopsy from the same incision site and a third biopsy from the contralateral leg. Expression markers of ER stress, inflammation, hypoxia, and adipokines were measured in these fat biopsies. In addition, we tested for signs of systemic ER stress and inflammation in plasma and in circulating monocytes. Results mRNA/18s ratios of IL-6, monocyte chemoattractant protein-1, CD-14, hypoxia-induced factor 1-α, the spliced form of Xbox protein-1, glucose-regulated protein 78, CEBP homologous protein, and activating factor-4 were all severalfold higher, whereas mRNA/18s ratios of adiponectin and leptin were lower in fat biopsies taken from the same site 4 h after the first biopsy but were unchanged in the second biopsy that was taken from the contralateral site. The biopsies were not associated with changes in plasma and monocyte IL-6 concentrations or in monocyte ER stress markers. Also, whole-body insulin-stimulated glucose uptake was the same in 15 subjects who had biopsies compared with 15 different subjects who did not. Conclusion Open, sc fat biopsies produced inflammation, hypoxia, ER stress, and decreased expression of adiponectin and leptin. These changes remained confined to the biopsy site for at least 4 h.

Centrolenidae and Allophrynidae constitute a a large clade of neotropical treefrogs of approximately 148 species. Althought some studies have been addressed phylogenetically this group, a comprehensive phylogenetic analysis including a total evidence aproach has never been presented. The objetives of this study was: 1) test previosly phylogentic hypothesis in Centrolenidae and Allophrynidae; ii) test the monophyly of both families; iii) perform a new phylogenetic analysis using both DNA and phenotipic evidence and iv) analize the evolution of some morphological and behavior characters consistent with the hypothesized relationships proposed. This phylogentic analysis was based in 378 terminals (268 of ingroup) representing 145 spepcies, 189 phenotipic characters and approximately 8500pb of 13 genes. The phylogenetic analysis resulted in 34 most parsimonious trees of 67.821 steps, which are summarized in a strict consensus cladogram. Concurring with previous studies, the Total Evidence phylogenetic analysis here performed corroborated the closely relationship between Allophrynidae and Centrolenidae families, it also corroborated the monophyly of subfamilies Hyalinobatrachiinae and Centroleninae. A new subfamily Allobatrachinae and new genus Allobatrachium are erected to allocate Allobatrachium sp, which form the sister taxon of all others centrolenids. Within Hyalinobatrachiinae, the genera Hyalinobatrachium and Celsiella are corroborated as monophyletic. Other results support a sister-group relationship between Ikakogi, Celsiella + Hyalinobatrachium. Whitin Centroleninae, two main clades were recovered: the first includes the tribe Cochranellini and the second another clade no named but composed of two mayors groups Nymphargus + Centrolene. Whitin Cochranellini, the analyses also corroborated the monophyly of Cochranella, Espadarana, Rulyrana, Sachatamia, Chimerella and Vitreorana but, Teratohyla is demonstrably nonmonophyletic: ((Chimerella (Teratohyla + Vitreorana)) (Teratohyla ((Cochranella + Espadarana) (Rulyrana + Sachatamia)))). To reconcile this situation, the genus Chimerella (one species) and two species of Teratohyla (T.amelie and T. pulverata) are placed in the synonymy of Vitreorana. Rulyrana is redefined and now includes 12 species by adding three species previously placed in Sachatamia genus.
A fam?lia Centrolenidae ? atualmente composto por 148 esp?cies; Allophrynidae, por sua parte, est? constitu?da por apenas tr?s esp?cies. Apesar de alguns estudos terem avaliado as rela??es destas duas fam?lias, uma hip?tese compreensiva para estas fam?lias incorporando a evid?ncia fenot?pica e a molecular nunca foi proposta. Os objetivos deste trabalho foram: i) testar a hip?tese de rela??es filogen?ticas previas de Centrolenidae e Allophrynidae; ii) testar a monofilia destas duas fam?lias; iii) propor uma hip?tese de relacionamento filogen?tico e iv) analisar a evolu??o de alguns caracteres morfol?gicos e comportamentais no contexto da nova hip?tese de rela??es a ser proposta. Para isto, foi realizada uma an?lise filogen?tica baseada em 378 terminais (268 do grupo interno, representando 145 esp?cies), 189 caracteres fenot?picos e sequencias de 13 genes (ca de 8500 pb). A an?lise clad?stica de parcim?nia deste estudo teve como resultado final 34 ?rvores igualmente parcimoniosas de 67.821 passos. As ?rvores mais parcimoniosas apresentaram conflito em quatro pontos no relacionamento interno apresentado pelas esp?cies de Hyalinobatrachium: H. fleischmanni e H. tatayoi; Espadarana: E. prosoblepon e E. callistoma; Rulyrana: R. adiazeta e R. susatamai e Centrolene: Centrolene sp4, Centrolene sp5 e C. condor. Assim como em trabalhos pr?vios, este estudo corroborou a estreita rela??o entre as fam?lias Allophrynidae e Centrolenidae. A fam?lia Centrolenidae e as subfam?lias Hyalinobatrachiinae e Centroleninae foram corroboradas como monofil?ticas. A nova subfam?lia Allobatrachinae e novo g?nero Allobatrachium s?o erigidos para alocar a esp?cie Allobatrachium sp, o t?xon irm?o de todos os centrolen?deos. Dentro de Hyalinobatrachiinae, os g?neros Hyalinobatrachium e Celsiella foram corroborados como monofil?ticos. Ikakogi foi recuperado como grupo irm?o Celsiella + Hyalinobatrachium. Dentro de Centroleninae, dois grandes clados foram recuperados: o primeiro deles apresenta a categoria taxon?mica de tribo Cochranellini, e o segundo n?o se encontra nomeado e est? conformado por Nymphargus + Centrolene. O monofiletismo destes dois ?ltimos grupos foi corroborado. Dentro de Cochranellini, o monofiletismo de Cochranella, Espadarana, Rulyrana, Sachatamia, Chimerella e Vitreorana tamb?m foi corroborado, mas, contrariamente, Teratohyla n?o foi corroborado como monofil?tico. As rela??es entre esses g?neros ? descrita como a seguir: ((Chimerella (Teratohyla + Vitreorana)) (Teratohyla ((Cochranella + Espadarana) (Rulyrana + Sachatamia)))). Para reconciliar esta situa??o, o g?nero Chimerella (uma esp?cie) e duas esp?cies do g?nero Teratohyla (T. amelie e T. pulverata) s?o alocadas na sinon?mia do g?nero Vitreorana. O g?nero Rulyrana ? expandido a 12 esp?cies ao incluir em sinon?mia as tr?s esp?cies atualmente reconhecidas do g?nero Sachatamia.

Resumen

ABSTRACT Background: The epicardial adipose tissue is located between the myocardium and the visceral pericardium, lying directly above the myocardium without any fascia. Epicardial adipose tissue presents itself with histological features typical of the brown adipose tissue. It plays a cardioprotective role through thermoregulation, energy homeostasis and anti-inflammatory regulation. However, in pathological conditions, epicardial adipose tissue may have a pro-inflammatory effect. Less is known about the role played by epicardial adipose tissue in patients with a history of atrial fibrillation. Some studies suggest an association between increased epicardial adipose tissue (volume and thickness) and atrial fibrillation. Nonetheless, there is little data about histological characterisation of epicardial adipose tissue in patients with a history of atrial fibrillation. Aim of the study: To evaluate the quantitative (using echocardiography) and qualitative characteristics (intra-operatory biopsy for histological characterisation) of epicardial adipose tissue in relation to atrial fibrillation burden after coronary artery bypass graft. Patients and methods: Prospective single-centre study approved by the ethics committee of Verona and Rovigo in July 2018. Patients undergoing coronary artery bypass graft with preserved left ventricular ejection fraction were included, after giving informed consent. Patients with atrial fibrillation and immunosuppressive therapy history were excluded. All enrolled patients underwent a medical evaluation to collect clinical history, a transthoracic echocardiography to measure epicardial adipose tissue thickness and collection of a bioptic sample containing right appendage and epicardial adipose tissue during coronary artery bypass graft. After surgery post-surgical clinical course and telemetry were collected. Lastly, histological characterisation (PLIN1 and fibrosis) of the bioptic samples was performed. Results: 56 patients undergoing coronary artery bypass graft were enrolled between 10th September 2018 and 3rd September 2019 in Cardiology and Cardiac Surgery departments. The mean hospitalisation was 11,9 ± 6,9 days and the postsurgical hospitalisation was 7,9 ± 3,7 days. 44 (78,6%) patients were male and the median age was 68,45 ± 9,2 years. All patients were continuously monitored with telemetry from the day of cardiac surgery until discharge. No major complications occurred, only one death unrelated to the surgery. Out of the total number of patients, 22 (39%) had at least one episode of atrial fibrillation. In the population that developed atrial fibrillation there was a bigger atrial volume, a higher degree of diastolic disfunction (E/A rate), a thicker layer of epicardial adipose tissue and an older median age in comparison to the group that did not develop it. Epicardial adipose tissue measured using echocardiogram with a cut off of 4 mm was a predictor of atrial fibrillation with an OR of 1,49 [1,09-2,04], 73% of sensibility and 89% of specificity. Furthermore, from the histological analyses of biopsies, the patients with atrial fibrillation had a significantly higher percentage of fibrosis, while adipose infiltration was not significantly higher. Through univariate analysis, atrial volume (OR 1,05 CI 1,01-1,09, p 0,022), E/A rate (OR 0,04 CI 0,02-0,72 p 0,29), the percentage of fibrosis (OR 1,12 CI 1,00-1,25 p 0,045) and age (OR 1,17 CI 1,07-1,28 p 0,001) were predictors of atrial fibrillation as well as the thickness of the epicardial adipose tissue. Through multivariate analysis atrial volume (p 0,027), fibrosis (p 0,003) and age (p 0,039) were independent predictors of atrial fibrillation. Conclusion: Post cardiac surgical atrial fibrillation is frequent. Epicardial adipose tissue measured by echocardiogram, atrial volume, fibrosis and age are predictors of post cardiac surgical atrial fibrillation.

Resumen

This thesis discusses the motivation, origin, history, design guidelines, API, the device drivers and userland utilities of the hardware sensors framework available in OpenBSD. The framework spans multiple utilities in the base system and the ports tree, is utilised by over 75 drivers, and is considered to be a distinctive and ready-to-use feature that sets OpenBSD apart from many other operating systems, and in its root is inseparable from the OpenBSD experience. The present framework, however, is missing the functionality that would allow the user to interface with the fan-controlling part of the hardware monitors. We therefore discuss the topic of fan control and introduce sysctl-based interfacing with the fan-controlling capabilities of microprocessor system hardware monitors. The discussed prototype implementation reduces the noise and power-consumption characteristics in fans of personal computers, especially of those PCs that are designed from off-the-shelf components. We further argue that our prototype is easier, more intuitive and robust compared to solutions available elsewhere.

Resumen

Imaging techniques play a key role in the assessment of patients with the idiopathic inflammatory myopathies (IIM). Magnetic resonance imaging (MRI) can reveal muscle inflammation similarly to muscle scintigraphy and 18F-Fluorodeoxyglucose positron emission tomography, but is also able to visualize findings of chronic muscle damage such as muscle atrophy or fat replacement. Ultrasonography has a more limited role because it can only depict the superficial muscle layers. Imaging findings are not specific to IIM, but in the appropriate clinical context they support the diagnosis. MRI is also useful to target biopsy to affected muscles, thus increasing biopsy yield. In addition, because different myopathies present with different patterns of muscle involvement, imaging studies can provide differential diagnostic clues. Finally, imaging studies—especially MRI—can be used to monitor the effects of treatment by serially evaluating changes in muscle inflammation and damage.

Resumen

Tumours of the central nervous system examines the epidemiology, aetiology, genetics and pathology of these heterogeneous tumours. Clinical presentation reflects the site of origin and rate of growth. Investigation usually comprises imaging (MRI superior to CT for most), and biopsy; requirement for additional staging depends on pathology. The treatment of low-grade gliomas may be delayed if small with few symptoms, otherwise surgery and/or radiotherapy. High grade gliomas may be managed with surgery, radiotherapy, and temozolomide chemotherapy in fit patients. Unfit patients should be offered supportive care only. Brief summaries are provided for management of ependymoma, pineal tumours, meningioma, germ-cell CNS tumours, pituitary tumours, CNS lymphoma, acoustic neuroma, medulloblastoma, and spinal cord tumours. Radiotherapy for primary CNS tumours is described along with its side effects, and chemotherapy for these diseases is reviewed. Brain metastases far outnumber primary brain tumours, with generally poor prognosis, but this relates both to the pathology and patient performance status. Appropriate treatment may include surgery, radiotherapy, and/or chemotherapy.

Resumen

Panniculitis is an inflammation that originates primarily in the subcutaneous fatty tissue (panniculus adiposus). It is associated with rheumatological diseases and with adverse events to rheumatological therapies (e.g. poststeroid panniculitis, erythema nodosum, infective panniculitis). The panniculitides are classified histopathologically into mostly septal panniculitis and mostly lobular panniculitis, according to the major or denser localization of the infiltrate, and also into those with or without vasculitis. Additional criteria involve the composition of the inflammatory infiltrate, the cause, and an underlying or associated disease. The clinical hallmarks of panniculitis are subcutaneous nodules or plaques, often located on the lower limb. A deep excisional biopsy is often required for a more precise diagnosis, given the often sparse and monotonous clinical symptoms. Erythema nodosum is the most common form and a typical example of septal panniculitis. It occurs in response to many different provoking factors, the most common trigger in children being a 'strep throat', in adults sarcoidosis. Clinically, it presents with a sudden symmetrical appearance of painful, tender, warm, erythematous nodes or plaques, usually on the shins, which resemble bruises. Classical and cutaneous polyarteriitis nodosa present a mostly septal panniculitis associated with vasculitis. Here subcutaneous, partially ulcerating nodules are surrounded by livedo racemosa. The mostly lobular panniculitides not associated with vasculitis include lupus panniculitis (lupus erythematosus profundus, typically with ensuing lipoatrophy and predilection for the upper part of the body), panniculitis in dermatomyositis (often calcifiying), cold panniculitis, pancreatic panniculitis, panniculitis due toα‎-antitrypsin deficiency, poststeroid panniculitis (in children after rapid withdrawal of corticosteroids), calciphylaxis (with and without renal failure), and factitious panniculitis (after mechanical, physical, or chemical injuries to the subcutaneous tissue, often self-inflicted). Nodular vasculitis (formerly erythema induratum Bazin) is a lobular panniculitis with vasculitis involving mostly the small blood vessels of the fat lobule. It appears to present a (hyper)reactive response to certain infections (tuberculosis, streptococci, candida) or to cold exposure or chronic venous insufficiency in susceptible females. In conclusion, the panniculitides are a heterogenous group of diseases requiring a systematic work-up and knowledge of certain histological or clinical criteria.

Resumen

Homo Sacer, Giorgio Agamben’s transformative twenty-year project in political ontology, is framed at its very outset in terms of Aristotelian philosophy – read, as we will see, from a strongly medieval, Heideggerian and Arendtian perspective. As a locus classicus of the juxtaposition of the two Greek terms for life, zoe (‘the simple fact of living common to all living beings’) and bios (‘the form or way of living proper to an individual or a group’), Agamben (HS 1–2) cites a passage in Aristotle’s Politics that notes that there is a certain ‘natural delight (euemeria) and sweetness’ in the ‘mere fact of being alive itself’ (to zen auto monon), which makes human beings hold on to it for its own sake, provided that the mode of life (bios) that this being-alive amounts to is not fraught with excessive difficulty.

Resumen

Eusebius refers to Philo far more frequently than any previous early Christian writer. In most of these citations, he describes Philo as a Hebrew. The chapter begins with an analysis of the clear distinction Eusebius draws between Hebrews and Jews. By describing Philo as a Hebrew, Eusebius associates him with a philosophical way of life, or bios, practiced before the institution of the Mosaic law and perpetuated by the Essenes, the Therapeutae, and ultimately, Eusebius’s Christian contemporaries. Philo the Hebrew is invoked to support Eusebius’s claim that the Christians are the legitimate heirs to the Hebrew scriptures, scriptures better understood by the Christians than by the Jews. When Eusebius cites Philo as a witness to the suffering of the Jews in the aftermath of Jesus’ crucifixion, however, he does not refer to him as a Hebrew.

Resumen

For three decades, award-winning independent filmmaker Todd Haynes, who emerged in the early 1990s as a foundational figure in New Queer Cinema, has gained critical recognition for his outsider perspective. Today, Haynes is widely known for bringing women’s stories to the screen. Analyzing Haynes’s films including Safe (1995), Velvet Goldmine (1998), Far from Heaven (2002), and Carol (2015), as well as his unauthorized Karen Carpenter biopic, Superstar (1987), and the television miniseries Mildred Pierce (2011), the contributors to Reframing Todd Haynes reassess his work in light of his long-standing feminist commitments and his exceptional career as a director of women’s films. They present multiple perspectives on Haynes’s film and television work and on his role as an artist-activist who draws on academic theorizations of gender and cinema. The volume illustrates the influence of feminist theory on Haynes’s aesthetic vision, most evident in his persistent interest in the political and formal possibilities afforded by the genre of the woman’s film. The contributors contend that no consideration of Haynes’s work can afford to ignore the crucial place of feminism within it. Contributors. Danielle Bouchard, Nick Davis, Jigna Desai, Mary R.

Resumen

Dermatofibrosarcoma (DFS) is a rare low-grade fibroblastic mesenchymal tumor derived from the dermis. The lesion accounts for approximately 1% of all soft-tissue sarcomas and less than 0.1% of all malignancies, with an annual incidence of 4.2–4.5 cases per million. It occurs most frequently between the second and fifth decades of life and usually appears in the dermis and subcutaneous tissue. DFS occurs more commonly in the trunk (42%–72%), and breast involvement is uncommon and occurs due to the infiltration of previous dermal involvement. We report a case of a 40-year-old female patient with a history of a violaceous nodulation that was hardened and not adhered to deep planes measuring approximately 5 cm in the inferomedial quadrant of the left breast, whose biopsy was performed in an external unit revealing a DFS. Magnetic resonance imaging of the breast showed a nodule with thickening of the adjacent skin in the aforementioned topography, measuring 3.1×3×2.9 cm, in addition to another nodular image with similar characteristics, compatible with multifocal involvement. She underwent quadrantectomy and immediate reconstruction with a myocutaneous flap of the fat-grafted latissimus dorsi muscle. A surgical specimen containing two nodules, measuring 2.8 and 2.5 cm, respectively, with a result compatible with a DFS with free surgical margins was analyzed. Immunohistochemistry revealed native estrogen and progesterone receptors, positive CD34 in tumor cells, and positive Ki67 in less than 5% of cells. The patient remains under clinical follow-up at our service, with no evidence of recurrence of the lesion, currently with annual consultations for physical examination and checking of breast ultrasound and bilateral mammography examinations.

Resumen

Introduction: The broad acceptance of sentinel lymph node biopsy (SLNB) led to an analysis for finding out the anatomopathological characteristics that can help predict the involvement of other axillary lymph nodes (LN) in positive sentinel lymph node (SLN) cases. Currently, it is very appropriate to investigate the cases that enable the omission of complete axillary dissection (CAD), even considering the involvement of the SLN. Some important studies on this theme were published, e.g., ACOSOG Z0011, and AMAROS. However, their results were not accepted uniformly enough because of methodological inconsistencies. Objectives: We aimed at providing a complementary basis for a pragmatic analysis of CAD after a positive SLNB in breast cancer. Methods: This is a cross-sectional study. Clinical and anatomopathological data were collected in patients with early-infiltrating breast cancer that were treated with SLNB, followed by CAD. Statistical analyses were performed using binary logistic regression and multiple logistic regression. Results: Out of 129 patients evaluated, compromise of non-sentinel additional lymph nodes was observed in 47 (36.4%) patients. According to an univariate analysis, the parameters related to non-SLN compromise were the tumor size in anatomopathological exam, histological grade III, the presence of peritumoral vascular embolism in focal area, compromise of more than one SLN, LN compromise rate of 100%, the presence of extracapsular neoplastic extension, perilymphnodal vascular involvement, perilymphatic fat compromise, and twenty or more dissected non-SNLs. The variables that increased the chance of compromise of non-SNL in the multivariate analysis were presented in following table with an accuracy of 81% (Figure). Conclusions: The tumor size on a clinical examination of the T2 category, the presence of two or more neoplastic foci in the SNL, and the size of the metastasis > 4.0 mm are the parameters that favor complete axillary lymphadenectomy.

Resumen

Context: Primary central nervous system angeitis (APSNC) is a vasculitis confined to the central nervous system (CNS). Its incidence rate is 2.4 cases per 1,000,000 person-years. It affects predominantly small and medium sized arteries of the cerebral parenchyma, spinal cord and leptomeninges. The most common manifestations are headache, cognitive impairment, stroke and transient ischemic attack. The fact that it results in multifocal inflammation of the arteries and veins can lead to ischemic or hemorrhagic infarctions in multiple vascular territories, more common in the subcortical white matter. Case report: A woman with a past of epilepsy and headache present to us with acute intraparenchymal hemorrhagic stroke, after extensive investigation, arrived at the presumed diagnosis of APSNC. Conclusion:Tests such as MRI and arteriography have low sensitivity and specificity for APSNC and brain biopsy is still the gold standard method for diagnosis, but in practice it is performed in less than half of the cases in clinical practice, this is due to several factors. Next, it is important to note that the biopsy efficiency is around 53-74% in unselected areas, reaching 80% if the site is selected affected by non-invasive exams. The literature specifies brain biopsy as a procedure with relatively low morbidity and mortality, however, it was not performed in more than a half of cases.

Resumen

Aims: Extra ovarian granulosa cell tumor (GCT) is extremely rare tumor, assumed to arise from the ectopic gonadal tissue along the embryonal route of the genital ridge. A case of extra ovarian granulosa cell tumor of omentum in a 69 year old female presented here. Materials and Methods: A 69 years old postmenopausal, hypertensive female presented with complaints of pain in right lumber and iliac region of one month duration. Pain was off and on and intermittent. The patient had a history of hysterectomy 12 years ago for fibroid uterus. Results: Ultrasound examination of abdomen showed a hypoechoic lesion of size 78.1 mm x 57.3 mm in right iliac fossa with mild thickening of surrounding omentum. Another hypoechoic lesion of size 36.7 mm x 22.9 mm was seen in retroperitoneal region in supero-medial aspect of right kidney. CECT abdomen showed heterogeneously enhanced nodular lesion of size 6.6 x 6.8 cm in right lumbar region, mild thickening of surrounded omentum also seen however there was no evidence of infiltration to bowel loop seen. Uterus was not visualized. PET CT whole body revealed mildly metabolically active enlarged nodes in the bilateral level ib an ii, metabolically active large lobulated heterogeneously enhancing soft tissue density lesion in right lumbar region with non enhancing areas of necrosis. The lesion is closely abutting the anterior abdominal wall musculature antero laterally and small bowel loop medially surrounding mesenty shows increased vascularity and haziness. Colonoscopy findings were normal. Trucut biopsy of mass right lumbar region was positive for malignancy likely Round cell Sarcoma. A provisional diagnosis of retroperitoneal sarcoma of right lumbar region was made. She underwent exploratory laparotomy with excision of tumor. As per Operative findings there was approximately 8 x 7 cm, firm, omental mass present right to midline, arising from under surface of greater omentum. Ovaries were normal. Gross examination of omental mass showed nodular mass measuring 8 x 5 x 6 cm. External surface was multinodular and cut surface was grey brown to grey yellow with solid cystic areas and areas of necrosis. Microscopic examination of specimen showed Extraovarian Adult granulosa cell tumor/metastasis from occult granulose cell tumor. On IHC Vimentin, CK, SMA, Inhibin were positive, Ki67:15%, ER/PR were also positive and are negative for calretinin, thromobomodulin. Extensive necrosis was seen. After that she underwent rexploration and total omenectomy. HPE showed fat necrosis in omentum. All investigation showed no evidence of tumor in ovaries and at any other primary site then the patient finally diagnosed as having Granulosa cell tumor involving only omentum post op stage III C. Then patient was given six courses of chemotherapy with Inj Paclitaxel and Inj Carboplatin three weekly. Now patient is on regular follow up and disease free. Conclusion: Extra ovarian adult granulosa cell tumor of omentum is rare tumor. Multimodal treatment approaches including surgery, multi-agent chemotherapy may provide a survival benefit for patients.

Resumen

Paget’s disease (PD) of the nipple is a rare cancer that affects the nipple and areola and accounts for between 0.4% and 5% of breast cancers. It was first described in 1877 by the English physician Sir James Paget. It affects women between 60 and 70 years of age and very rarely affects men. In PD, the skin on the nipple and areola becomes thicker. Clinical presentations are usually erythema, desquamation, or eczematous changes in the nipple, features that can progressively progress to erosion, overt destruction, and ulceration of the papilla. Bloody papillary discharge, itching, nipple retraction, and/or a palpable mass may be associated. Cancer cells, called Paget cells, are malignant, large, with clear, abundant cytoplasm and nuclei with prominent nucleoli. Like glandular cells, they appear either as isolated cell in the epidermal tissue or as groups of cells. Most women diagnosed with PD also have ductal adenocarcinoma, either in situ or invasive. The prevalence is 67–100% of cases, which gives a worse prognosis to the patient. Patients with Paget-associated invasive breast disease have lower hormone receptor expression, greater lymph node involvement, and higher human epidermal growth factor receptor type 2 (HER2) expression. An 82-year-old woman sought the mastology outpatient clinic for a follow-up of carcinoma in situ in the right breast 2 years ago, having been submitted to quadrantectomy and hormone therapy with tamoxifen, with no signs of recurrence. She complained of an exudative pruritic lesion on the left nipple that had started 6 months ago. She reported that the lesion started with itching and burning, associated with a spontaneous discharge of serous secretion from the itchy surface of the breast, which improved with the use of “talcum powder.” On physical examination, the presence of a discrete reddened area with a diameter of 3 mm, eczematous, with bloody areas interspersed with serous secretion was observed on the left nipple. Areola lesions and palpable nodules in the left breast were absent. She underwent mammography, which showed symmetrical breasts with fat-replaced parenchyma, absence of nodules, presence of isolated calcifications, and grouping in the superior lateral region of the left breast, categorized as BIRADS II. On ultrasound, a nodule with angled edges, measuring 5×4 mm in the superomedial quadrant of the left breast, which showed nodular enhancement and persistent kinetic curve on magnetic resonance imaging of the breasts. The histopathological study diagnosed moderately differentiated left breast ductal carcinoma, associated with a high-grade solid intraductal carcinoma and PD of the nipple, without the involvement of the areola. Immunohistochemistry revealed the absence of estrogen and progesterone hormone receptors and HER-2 overexpression in both histological types. She underwent mastectomy with sentinel lymph node biopsy that was free of neoplasia. Oncological follow-up with no signs of recurrence. PD, if left untreated, extends to the areola and other regions of the breast. Therefore, clinical suspicion from the first physical examination allows an early diagnosis of extreme importance, which improves the prognosis and allows less aggressive treatments.
