Metastatic testicular Sertoli-cell tumor: cytopathologic findings on fine-needle aspiration

A sub-hepatic nodule in a young female: Chase the case

Sertoli-Leydig cell tumours (SLCTs) are rare, mixed sex-cord stromal tumours composed of varying proportions of both Sertoli and Leydig cells, which account for <0.5% of all ovarian tumours. The cytomorphologic features of SLCTs are not well described in literature. Herein, we describe the cytomorphologic features of an SLCT at an uncommon metastatic site in a young female.

Cytologic features of needle aspiration of ovarian sex cord tumor with annular tubules: Report of two cases and literature review

Sex cord tumor with annular tubules (SCTAT) is a rare ovarian tumor with characteristic microscopic morphologic features. Diagnosis most often is based on examination of tissue specimens. Cytologic features of this tumor rarely have been described in the English literature. Herein, we report cytologic findings of cyst aspiration fluid in two cases of SCTAT, with cyto-histologic correlation.

Metastatic ovarian Sertoli-cell tumor: FNA findings with immunohistochemistry

A malignant Sertoli cell tumor of the ovary is a rare sex-cord stromal derived neoplasm. Sertoli cell tumors account for approximately 4% of Sertoli-stromal cell tumors (Hsu et al., J Histochem Cytochem 1981;29:577-580). The diagnosis of this entity by fine-needle aspiration and needle core biopsy can be difficult when the differential also includes a metastatic renal cell carcinoma, due to the overlap of both cytological and histological features. Here, we show that immunohistochemical staining on cytological material including alpha-inhibin can be used to differentiate between these two malignant tumors.

Pelvic washing cytology of ovarian Sertoli-Leydig-cell tumor with retiform pattern: a case report

A Sertoli-Leydig-cell tumor is an exceptionally rare neoplasm. We present the pelvic washing cytomorphology of an ovarian Sertoli-Leydig-cell tumor with a retiform pattern in a 24-yr-old female. The cytologic features in this case were tight tissue fragments composed of small, relatively uniform cells with scanty cytoplasm and small rounded or blunt papillary fragments with hyalinized cores lined with small, mildly atypical cuboidal cells. Differential diagnoses included borderline and well-differentiated papillary serous tumors, clear-cell carcinoma, and collagen balls. Correlation of cytologic findings with histomorphology is crucial for correct interpretation of pelvic washings in cases of Sertoli-Leydig-cell tumors.
