Radiation-related changes including fibrosis, nuclear enlargement, hyperchromasia and cytoplasmic vacuolization may alter the appearance of normal ovarian tissue and ovarian tumors. We describe radiation-related changes in ovarian stromal neoplasm with mixed features of sclerosing stromal tumor and fibrothecoma. The right ovarian mass was discovered in a 38 year-old woman with past history of i...

A case of sclerosing stromal tumor of the ovary in a Chinese girl of 17 years is reported. She presented with metrorrhagia and an abdominal mass in the right lower quadrant. At operation, a large unilocular cyst was found in the right ovary. Light microscopic and ultrastructural study established the diagnosis of sclerosing stromal tumor of the ovary. To date, 63 cases have been recorded in the...

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...

Sclerosing stromal tumor of the ovary is a rare ovarian disease with prevalence of 1.5% to 6% of ovarian stromal tumors. We present a 24-year-old woman with irregular menstruation for 6 months and a self-palpable lower abdominal mass. Enucleation of the left ovarian tumor was undertaken. Gross examination showed a soft elastic tumor with a smooth outer surface and diffusely white edematous stro...

Sclerosing stromal tumor (SST) of the ovary is a very rare sex cord stromal tumor occurring in a younger age group than other types of stromal tumors and most commonly accompanied by menstrual irregularity. Several unique histologic features including pseudolobulation, sclerosis and prominent vascularity are clearly reflected at ultrasonography and MRI. We report the ultrasonographic and MR fea...

Background: Spindle cell/Sclerosing rhabdomyosarcoma is the rarest variant of rhabdomyosarcoma, accounting for 5-10% all cases. Pathologically, these tumors can provide a variety features and resemble other tumors, thus often difficult to diagnose. We report case sclerosing gingiva with histomorphology mimicking malignant peripheral nerve sheath tumor. Case Presentation: The patient was 39-year...

Ovarian tumors are classified on the basis of tumor origin as epithelial tumors (serous and mucinous tumors, endometrioid and clear cell carcinomas, Brenner tumor), germ cell tumors (mature and immature teratomas, dysgerminoma, endodermal sinus tumor, embryonal carcinoma), sex cord-stromal tumors (fibrothecoma; granulosa cell, sclerosing stromal, and Sertoli-Leydig cell tumors), and metastatic ...
