BACKGROUND Ovarian sex-cord stromal tumors (SCST) are rare in childhood and include a variety of neoplasms with different clinical features and biologic behavior. Aim of the analysis was to report the clinical findings and treatment results of a series of patients with SCST of the ovary, registered in a multi-institutional Italian network on rare tumors in children and adolescent between 2000 a...
A 34-year-old man underwent left hemicastration for malignant unclassified sex cord gonadal stromal tumor. At 6 months pulmonary metastases developed and the patient received 3 courses of chemotherapy consisting of cisplatin, bleomycin and etoposide. A residual focus in the right lung was excised and proved to be viable tumor. He then received 2 adjuvant courses of cisplatin, etoposide and ifos...
We Describe a case of ovarian serous cystadenoma having Sertoli-Leydig cell tumor, well differentiated, in the cystic septum. Well differentiated Sertoli-Leydig cell tumor coexisting with other tumor, including serous tumor, has not yet been described. In all cases of Sertoli-Leydig cell tumor with heterologous components or other tumors, the androblastomatous components are intermediately or p...
BACKGROUND Ovarian Stertoli-Ledig cell tumor (SLCT) is a rare type of sex cord-stromal tumor of the ovary. The present study was to evaluate clinicalopahologic features and prognosis of patients with Sertoli-Leydig cell tumor treated by surgery and adjuvant chemotherapy during short term follow-up. METHODS A total of sixteen patients with ovarian Sertoli-Leydig cell tumor treated at the Obste...
Steroid cell tumors account for less than 0.1% of all ovarian tumors. There are three steroid cell tumor subtypes: steroid cell tumor not otherwise specified (NOS), stromal luteoma and Leydig cell tumor. Steroid cell tumor, NOS, is the most common type and has malignant potential. This report describes a case of an ovarian steroid cell tumor, NOS. A 35-year-old woman visited hospital with the c...
Ovarian sex cord-stromal tumors are relatively infrequent neoplasms that account for approximately 8% of all primary ovarian neoplasm. Sex cord-stromal tumors of the ovary include granulosa cell tumors, fibrothecomas, Sertoli-Leydigcell tumors, steroid cell tumors, and sclerosing stromal tumors (SST). Sclerosing stromal tumors account for 2% to 6% of ovarian stromal tumors. Despite the rarity o...
The diagnosis and subclassification of Sertoli cell tumors (SCT) of the testis are often challenging to general surgical pathologists because of the rarity of the tumors. Immunohistochemical study to date has limited diagnostic value. Nuclear localization of β-catenin, which correlated closely with CTNNB1 gene mutation, was recently reported in SCTs. We investigated the utility of β-catenin nuc...
Sertoli cell tumors of the testis are extremely rare tumors with a heterogeneous pathology. Three histological variants have been described: Sertoli cell tumor not otherwise specified (NOS), large cell calcifying sertoli cell tumor and the Sclerosing Sertoli cell tumor. The sclerosing Sertoli cell tumor described herein is associated with prominent stromal sclerosis. They present as painless...
Leydig cell tumors are usually benign tumors of the male gonad. However, if the tumor is malignant, no effective treatments are currently available. Leydig cell tumors express platelet-derived growth factor (PDGF), kit ligand and their respective receptors, PDGFR and c-kit. We therefore evaluated the effects of imatinib mesylate (imatinib), a selective inhibitor of the c-kit and PDGFR tyrosine ...
the sex cord-like variant of endometrioid carcinoma is a rare subtype with a close histological resemblance to the sex cord-stromal tumor of the ovaries, in particular the sertoli cell tumor. however, very few cases of the granulosa cell tumor-like variant have been reported since it is commonly misdiagnosed as a granulose cell tumor. immunohistochemistry is useful in the diagnosis of these tum...
