background : this study evaluates estrogen and progesterone expressions in patients with ovarian tumors (both benign and malignant) and their correlation with various clinicopathological prognostic parameters. receptors for estrogen and progesterone are predictive and prognostic markers of endometrial and breast cancers. however, their clinical significance in epithelial ovarian cancer is not c...
Background & Objective: The common epithelial ovarian tumors are classified into serous, mucinous, clear cell, endometrioid, the Brenner, mixed, and undifferentiated types. Cytoskeleton intermediate filament composition of ovarian tissues indicates that the cytokeratin and vimentin are observed in ovarian surface epithelium along with the common ovaria...
Virilism is the masculinization and enhancement of male secondary sexual characteristics in females. The etiology is usually of adrenal or ovarian origin. Here we report a case of virilizing Leydig cell type, steroid cell tumor of the left ovary, in a 40 year old female who presented with clinical signs and symptoms of virilization: deepening of voice, hirsutism (Ferriman-Gallwey score 26), cli...

Premenopausal onset is rare and the present study described two cases of ovarian clear cell tumors in young women. Case Presentation: The patients presented with pelvic mass which was confirmed by sonography and laparotomy and final diagnosis was ...
objective: to evaluate the potentiality of ovcar–3 cell line of ovarian adenocarcinoma as a xenograft model for ovarian adenocarcinoma in nude mice. materials and methods: the cell line isolated from advanced human ovarian adenocarcinoma, were inoculated to eight nude mice and two months later. established tumors were transferred to pathology laboratory to be prepared by h&e; staining and immun...
Background: Ovarian mucinous borderline tumors are divided into two morphologic groups: endocervical-like and intestinal type. Most endocervical adenocarcinomas exhibit mucinous and/or endometrioid differentiation, they infrequently metastasize to the ovaries but may simulate primary ovarian tumors (both atypical proliferative or borderline and carcinoma). In patients with mucinous adenocarcino...
Background: Ovarian masses requiring surgical intervention are uncommon in the pediatric population. The aim of this study was to report results of a multicentric Tunisian study concerning the clinical practice and the management of pediatric ovarian masses and to identify the factors that are associated with ovarian preservation. Materials and Methods: Between January 2000 and December 2015...
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...
Background: Steroid cell tumor is one of the rare ovarian tumors and forms 0.1% of all ovarian tumors, divided to three subgroups. Steroid cell tumor that are not otherwise specified (NOS) are the most common type and represent 60% of steroid cell tumors. One of the most known signs of this tumor is hormonal function, especially androgenic effects of it. Primary treatment consists of eradicatio...
