Surface epithelial tumors account for more than 90% of ovarian tumors, of which serous tumors comprise 46%. Sex-cord stromal tumors constitute 8% of ovarian tumors, fibroma being the commonest, comprising 70% in this category. Combination of different types of tumors can occur in ovary with most common being Mucinous cystadenoma and Brenner tumour. We report a case of a very rare combination of...

The molecular genetic events involved in the etiology of granulosa cell, Sertoli cell, and Leydig cell tumors are unknown. The expression of the Wilms' tumor suppressor gene WT1 in granulosa and Sertoli cells prompted us to analyze this gene for mutations in 11 granulosa cell tumors, three Leydig cell tumors, and one Sertoli/Leydig cell tumor. Although most of these tumors express WT1 mRNA, non...

BACKGROUND To retrospectively investigate reproductive outcomes after fertility-sparing surgery and postoperative adjuvant chemotherapy in malignant ovarian germ cell tumors (MOGCT) and sex cord-stromal tumors (SCST). METHODS Data from 32 MOGCT (6 dysgerminomas, 6 yolk sac tumors, 17 immature teratomas, and 3 mixed germ cell tumors) and 9 SCST (4 granulosa cell tumors and 5 sertoli-leydig cel...

background: tumors of the central nervous system (cns) are a heterogeneous group of neoplasms with different prevalence in different sex and age groups and various parts of cns. objectives: determining the relative frequency of different types of cns tumors in different ages, sex and cns anatomical locations. materials and methods: this retrospective study was performed using pathological repor...

Neural-cadherin is a member of the cadherin gene family encoding the N-cadherin protein that mediates cell adhesion. N-cadherin is a marker of Sertoli cells and is also expressed in germ cells of varying stages of maturation. The purpose of this study was to determine the presence and distribution of this protein by immunohistochemistry in 105 germ cell tumors of both single and mixed histologi...

introduction: numerous studies have investigated the prevalence, incidence and clinical manifestations of gastrointestinal stromal tumors (gists). however, little is known about gists in iran. this pioneer study focuses on description of 36 patients with gists in iran. methods: a database was created for 36 patients suffering from gist who were treated in loghman medical center and tehran cance...

•Endometrial stromal sarcoma (ESS) may have sex cord differentiation, usually focal.•Diagnosis of ESS is difficult when variant morphology predominates.•Prognosis differs between ESS and UTROSCT; therefore, distinction is critical.•Extensive tumor sampling is mandatory to identify neoplastic endometrial stroma.•Sex cord differentiation may be associated with endometrial hyperplasia.

Sertoli cell tumor, also termed androblastoma or gonadal stromal tumor, is a rare testicular neoplasm. While it is usually benign, 25 cases of malignant Sertoli cell tumors have been reported.'" These neoplasms vary greatly in microscopic appearance and unfortunately they have aggressive metastatic behavior. Despite various treatments, the prognosis remains poor. We report on the fourth prepube...
