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...

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...

Ovarian sex cord-stromal tumors are infrequent and represent approximately 7% of all primary ovarian tumors. This histopathologic ovarian tumor group differs considerably from the more prevalent epithelial ovarian tumors. Although sex cord-stromal tumors present in a broad age group, the majority tend to present as a low-grade disease that usually follows a nonaggressive clinical course in youn...

OBJECTIVE Alpha-inhibin and calretinin have been traditionally used as immunomarkers for sex cord stromal tumors. However, the variation in their immunoreactivity and their lack of specificity for sex cord stromal tumor makes the search for a more sensitive and specific immunohistochemical marker essential in routine diagnosis of sex cord stromal tumor. This study was conducted to correlate the...

background and objective: histopathological evaluation of granulosa cell tumors (gct) of the ovary may be confused morphologically with a wide variety of the tumors. immunohistochemical staining for inhibin and calretinin can be used for better diagnosis. although it has been suggested that inhibin can be a sensitive marker for gct, it maybe had negative results in some cases.  in addition, cal...

BACKGROUND Ovarian sex cord stromal tumors are rare neoplasms as compared to epithelial tumors. No large study has been done in Pakistan to find out the frequencies of various sex cord stromal tumors and their clinicopathological behavior in our region. The purpose of our study was to determine the various histological patterns and clinical features of ovarian sex cord stromal tumors along with...

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...

A 34-year-old tetraplegic patient with suppurative epididymitis was found on follow-up examination and ultrasonography to have a testicular mass. The radical orchiectomy specimen contained an undifferentiated spindled sex cord-stromal tumor arising in the rete testis. Testicular sex cord-stromal tumors are far less common than germ cell neoplasms and are usually benign. The close relationship b...

Uterine and extrauterine tumors composed of cells featuring endometrial stromal cells often show ovarian sex cord-like structures and smooth muscle differentiation. A few cases of endometrial stromal tumors showing rhabdoid differentiation have been reported. The present case is a 20-year-old woman with endometrial stromal sarcoma that had sex cord-like structures, smooth muscle components and ...

Endometrial stromal sarcomas account for 0.25% of all uterine malignancies. These tumours were originally divided into low grade and high grade stromal sarcomas, but the recent World Health Organisation classification (2003) recognises low grade stromal sarcoma and undifferentiated endometrial sarcoma. Low grade sarcomas may exhibit other forms of differentiation, including smooth muscle and se...
