AbstractHistological examination of bone tumors is considered to be a challenging field inpathology. Bone tumors andtumor – like lesions are very rare. The low incidence of these tumors and the resulting limited experience indealing with them adds to the diagnostic difficulties.Clinico–radiological evaluation of bone tumors and tumor – like lesions is an essential part of patientmanagement. Histopathological diagnosis should be given after proper review of clinical and radiologicalfindings.There is very good correlation between clinico – radiological and histopathologic

Résumé :

Abstract: Among the most tedious and time-consuming tasks in medical image processing is brain tumor identification and segmentation. Magnetic resonance imaging, or MRI, is a medical procedure that radiologists primarily utilize to examine the human body without having to do surgery. The substantial information that MRI provides on human soft tissue aids in the diagnosis of brain tumors. It is crucial to accurately segment MRI images in order to detect a brain tumour utilizing computeraided clinical techniques. Brain tumor identification facilitates determining the precise size and location of

Résumé :

Lipomatous tumors are among the most common soft tissue tumors (STTs). Magnetic resonance imaging (MRI) is a state-of-the-art diagnostic tool used to differentiate and characterize STTs. Radiological misjudgment can lead to incorrect treatment. This was a single-center retrospective study. Two hundred and forty lipomatous tumors were included. MRI diagnoses were categorized as benign, intermediate, or malignant and were compared with histological diagnoses. Tumor volumes were measured by MRI and from surgical specimens. The tumor was correctly categorized 73.3% of the time. A total of 21.7% of

Background: The diagnosis of skin adnexal tumors is usually based on histopathology.

We report a case with primitive neuroectodermal tumor (PNET) of the parotid. We analyze through this observation the clinical, histological and therapeutic characteristics of this entity.

Résumé :

Pancreatic (islet-cell) and gastrointestinal endocrine tumors are quite rare diseases - the incidence of new cases is from 0.4 to 1.5 per 100,000 inhabitants. Instead of the broader term APUDomе, the term gastroenteropancreatic endocrine tumors (GEPET) has recently become more commonly used in clinical literature for practical reasons. As a result of numerous clinical and fundamental studies, about 19 types of GEPET and more than 40 products of their secretion are currently described. Most tumors are characterized by multihormonal secretion, but the development of the endocrine syndrome clinic

Résumé :

Three hundred and one salivary gland lesions (162 benign, 72 malignant, and 67 benign non-neoplastic) of 677 cases were evaluated by use of intraoperative frozen sections by 66 pathologists. In seven patients, the diagnosis was deferred for permanent sections. In four cases (1.3%), the diagnosis at permanent section changed from one category of benign tumor to another, and in five cases (1.7%), from one category of malignant tumor to another. In four tumors, a frozen section diagnosis of benign was changed to malignant on permanent sectioning; all four involved acinic cell carcinomas. Only two

Résumé :

To study the diagnostic capabilities of planar breast scintigraphy and single photon emission computed tomography (SPECT) with 99mTc-MIBI in visualizing of breast tumors, 61 patients with a diagnosis of breast cancer were included in the study. The results showed that sensitivity of the planar mode in identifying primary breast tumors was 46%. The sensitivity of SPECT in detecting primary tumor was 93.4%. The sensitivity of the planar mode in visualization of nodal metastases was 44.8%, against 93.1% in SPECT. This study showed that SPECT has a high diagnostic efficiency in regard of visualiza

Résumé :

Introduction. Multiparametric comparative analysis of clinical and molecular genetic biomarkers of malignant tumors has strong diagnostic and prognostic potentials and is a prerequisite for the development of personalized medicine. This approach makes it possible not only to simultaneously detect the expression of several tumor biomarkers, but also to obtain data on their spatial distribution in tissues examined, as well as to estimate the mutual location of tumor cells and tumor microenvironment expressing specific biomarkers. Thus, multiparametric immunohistochemical analysis (IHCA), which a

Résumé :

Malignant tumors rank as a leading cause of death worldwide. Accurate diagnosis and advanced treatment options are crucial to win battle against tumors. In recent years, Cherenkov luminescence (CL) has shown its technical advantages and clinical transformation potential in many important fields, particularly in tumor diagnosis and treatment, such as tumor detection in vivo, surgical navigation, radiotherapy, photodynamic therapy, and the evaluation of therapeutic effect. In this review, we summarize the advances in CL for tumor diagnosis and treatment. We first describe the physical principles

Résumé :

Krukenberg tumors are metastatic tumors of the ovaries, associated with poor outcomes. Most commonly, these tumors are of gastric origin. The diagnosis of Krukenberg tumors in pregnant patients is extremely rare and poses specific difficulties for clinicians. We report a case of a pregnant woman presenting with an unknown abdominal tumor. Through the use of magnetic resonance imaging, multiple differential diagnoses were proposed, including a malignant ovarian tumor. A cesarean section and explorative laparotomy were conducted, revealing Krukenberg metastases of a gastric tumor, discovered dur

Uterine leiomyomas are the most common type of benign tumor that occurs in the female pelvis. Uterine leiomyoma is a tumor of smooth muscles. Its prevalence is higher in the reproductive age group and decreases after menopause. Giant uterine fibroids are a rare tumor of the uterus. Giant uterine fibroids, especially subcutaneous types, are complicated by malnutrition due to deterioration of their blood supply. The complaints of the patients are non-specific: an increase in the size of the abdomen, aching pains, sometimes difficulty urinating and defecating. A physical examination reveals a gia

The juxtaglomerular cell tumor (JGCT) is a rare renal tumor characterized by excessive renin secretion causing intractable hypertension and hypokalemia. However, asymptomatic nonfunctioning JGCT is extremely rare. Here, we report a case of nonfunctioning JGCT in a 31-year-old woman. The patient presented with a left renal tumor without hypertension or hypokalemia. Under a clinical diagnosis of renal cell carcinoma, radical nephrectomy was performed. The tumor was located in the middle portion adjacent to the renal pelvis, measuring 2 cm in size. Pathologically, the tumor was composed of cuboid

The aim of the study is to identify clinical signs of neurilemmoma of the upper limb, its main ultrasound and X-ray distinctions from other benign tumors of soft tissues. To make a preliminary diagnosis, it is advisable to use different methods of imaging, such as: ultrasound, MRI, radiography. Radiological diagnosis of soft tissue tumors should be based on the integrated use of radiological and ultrasound methods with mandatory consideration of clinical and anamnestic data such as patient age, topographic location of the tumor and its growth rate.
