Conservative Management of Ovarian Fibroma in A Case of Gorlin-Goltz Syndrome Comorbid with Endometriosis

Ovarian fibromas are the most common benign solid ovarian tumors, which preoperative diagnosis often is difficult. Ovarian fibromas, especially in bilateral cases, may be representative of Gorlin syndrome.Gorlin syndrome (GS) is a rare autosomal dominant disorder with predisposition to basal cell carcinomas (BCCs) and other various benign and malignant tumors. To report a case of a young patien...

New insights into ovarian cancer pathology.

Malignant epithelial tumors (carcinomas) are the most common ovarian cancers and also the most lethal gynecological malignancies. Based on histopathology and molecular genetic alterations, ovarian carcinomas are divided into five main types [high-grade serous (70%), endometrioid (10%), clear-cell (10%), mucinous (3%), and low-grade serous carcinomas (<5%)] that account for over 95% of cases. Th...

Rare in Other Common Gynecological Malignancies Are Frequent in Endometrial Carcinoma

Loss of heterozygosity of chromosome lOq has been reported in ap proximately 40% of endometrial carcinomas. PTEN, a candidate tumor suppressor gene located at chromosome 10q23.3, was recently identified and found to be homozygously deleted or mutated In several different types of human tumors. To determine If PTEN is a target of lOq loss of heterozygosity in carcinomas of the endometrium, we ex...

Ovarian Carcinoma: Recent Developments in Classification of Tumour Histological Subtype

Histological types of ovarian carcinomas are distinct entities with different molecular and immunohistochemical profiles and clinical outcomes. The implementation of subtype-specific therapies for subtypes of ovarian cancer requires reproducible histological diagnoses. More than 95% of ovarian carcinomas can be reproducibly diagnosed as one of five histological types, in descending order of fre...

Histopathological Study of Gynecological Cancers in Patients Admitted to Baqiyatallah Hospital in Tehran during 2011-2019

Background and Objective: Each type of cancer has its own histopathological findings that determine the type of treatment regimen and the course of the disease. The present study aimed to histopathologically determine the types of gynecological cancers in patients admitted to Baqiyatallah Hospital over a nine-year period. Materials and Methods: This retrospective study was conducted based on h...
