Sertoli and Leydig cells, the two major somatic cell types in the testis, have different morphologies and functions. Both are essential for gonad development and spermatogenesis. However, whether these cells are derived from the same progenitor cells and the mechanism regulating the differentiation between these two cell types during gonad development remains unclear. A previous study showed th...

Sertoli-Leydig cell tumor of the ovary is a kind of sex cord-stromal tumor, which occurs between teens and twenties with symptoms including abdominal pain and swelling. The incidence rate is infinitely rare comprising less than 0.5% of all ovarian tumor. The average age of “retiform Sertoli-Leydig cell tumor” is 17 years as compared to 25 years for Sertoli-Leydig cell tumors as a group. We have...

Here we describe the case of a 19-year-old woman with a poorly differentiated ovarian Sertoli-Leydig cell tumor and an elevated serum alpha-fetoprotein level. The patient presented with diffuse abdominal pain and bloating. Physical examination, ultrasound, and magnetic resonance imaging revealed a right ovarian tumor that was histopathologically diagnosed as a poorly differentiated Sertoli-Leyd...

Introduction Large cell calcifying Sertoli tumors are exceedingly rare. They most commonly benign, but risks for malignancy include older age, larger size of tumor, and solitary tumors. To the author's knowledge, this is first case reported an incidental large tumor when orchidectomy was performed a separate lesion. Case presentation A 31‐year‐old male presented with painless testicular lump. U...

objective(s) this investigation was conducted to evaluate the effects of diabetes on the structure and function of testicular tissue. materials and methods diabetes was induced in male adult rats by a single intraperitoneal injection of streptozotocin. body and testicular weight, hormonal analyses, histological and ultrastructural analyses were measured. results the body and testicular weights ...

Sertoli-Leydig cells tumors are rare ovarian neoplasms that can be managed with conservative resection given their generally excellent prognosis. Here we report a case of Sertoli-Leydig cell tumor mistakenly diagnosed as an invasive mucinous adenocarcinoma at time of intraoperative consultation because of its blue-mucinous appearance in the frozen section material. The patient subsequently unde...

Sertoli-Leydig tumors tend to relapse early and due to their rarity, limited data are available regarding a role of chemotherapy in the management of Sertoli-Leydig cell tumors. We present a case of recurrent ovarian Sertoli-Leydig cell tumor whose salvage treatment was successful with paclitaxel and carboplatin chemotherapy.

The diagnosis of a testicular sclerosing Sertoli cell tumor is rare. Approximately 17 cases have been previously described in the literature worldwide. We present a case and review the evaluation and surgical management of a sclerosing Sertoli cell tumor presenting in a 26 year-old African-American adult, in association with testicular microlithiasis and oligospermia. Imaging techniques and the...

Ovarian sex cord-stromal tumors arise from the stromal cells that surround and support the oocytes. Sertoli-Leydig cell tumors belong to this category of ovarian neoplasms. We present the case of a 38-year-old woman who was found to have a right ovarian mass. The mass was resected and diagnosed as Stage I Sertoli-Leydig cell tumor, retiform variant, following histopathologic and immunohistochem...
