AIMS To describe a case of recurrent sarcomatoid adult granulosa cell tumour (AGCT) of the ovary and to evaluate the usefulness of two ovarian sex cord stromal markers (inhibin and calretinin) in separating sarcomatoid AGCT from true sarcomas. METHODS A 72 year old woman presented with a recurrent sarcomatoid AGCT in the sigmoid colon mesentery, which histologically mimicked a malignant gastr...

Purpose: To assess the recurrence and birth rates among patients with non-epithelial ovarian cancer. Methods: The study included 146 germ cell (GCT, n = 84) sex cord-stromal tumors (SCST, 62), who underwent fertility-sparing surgery. Adjuvant chemotherapy was administered to 86 (58.9%) patients. Most cases (133 out of 146) were staged FIGO I. Results: 5- 10-year disease-free survival 91% 83%, r...

The National Toxicology Program (NTP) classification system for rat and mouse ovarian tumors is presented. The classification system is based on previous classification systems and on a review of all the primary ovarian tumors from the archives of the National Cancer Institute (NCI) and NTP Carcinogenesis Testing Programs. The relative frequency and principal diagnostic features of 204 ovarian ...

Ovarian granulosa cell tumor (GCT) is a rare, low-grade malignant that accounts for 70% of the sex cord-stromal tumors. It has two histopathologic types with different clinical and biologic features: adult GCT juvenile GCT. Most women diagnosed have favorable prognosis, 5-year survival rate 97%–98%, but feature late relapse; recurrence time could be more than 20 years after diagnosis. Juvenile ...

One of the unusual variant of ovarian tumor is sex cord stromal tumor with annular tubules (SCTAT). The recurrence in case of malignant ovarian SCTAT ranges from 3mo to 20yr. This report describes the case of recurrence of SCTAT in a 35yr old woman after 4yr of hysterectomy with bilateral salphingo-Oopherectomy. Microscopic examination revealed features of SCTAT. Because of its unusual behavior...

the gastrointestinal stromal tumor (gist) is a rare mesenchymal tumor of gastrointestinal (gi) tract. this tumor has tendency to liver metastasis and peritoneal recurrence, however; the primarily lymph node involvement or metastasis is rare. here we reported a 17-years-old girl with multifocal gastric gist and multiple lymph node involvement at presentation and recurrence in celiac lymph nodes....

Sclerosing stromal tumor (SST) is an extremely rare and distinctive sex cord stromal tumor, occurring predominantly in the second and third decades of life. In this article, our aim is to present clinicopathologic features of STT, and to review the recent literature with regard to differentiating STT from other ovarian stromal tumors. We describe STT in a 17-year-old girl who presented with an ...
