The granulosa cell tumor is the most common malignant functioning tumor of the ovary. When functional, granulosa tumor almost always are estrogenic although rare tumors are androgenic. Progesterone producing by these tumors has only been reported twice. We report a case of granulosa cell tumor in a 7 years old girl with precocious puberty who represent the first case of progesterone producing b...

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...

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...

Granulosa cell tumor, a sex cord stromal estrogen secreting tumor presents with vaginal bleeding and is seen in all ages. It accounts for <5% of ovarian neoplasm. We reported rare case granulosa postmenopausal woman undergoing staging laparotomy total abdominal hysterectomy bilateral salpingo-oopherectomy malignant which was complicated by torsion, rupture hemorrhagic ascitis.

Granulosa cell tumors of the ovary are malignancies that originate from the sex-cord stromal cells of the ovary and represent 2% to 5% of all ovarian cancers. Slow growth with a tendency for late recurrence characterizes a natural history of this tumor. So this tumor needs a prolonged follow-up. As a result of recent literature in Korea, the findings are 3 cases of juvenile granulosa cell tumor...

Granulosa cell tumors are rare ovarian malignancies. Their characteristics include unpredictable late recurrent and malignant behavior. Recent molecular studies have characterized the FOXL2 402C > G mutation in adult-type granulosa cell tumor. In this study, we report an 80-year-old woman with a granulosa cell tumor arising from ovary. She presented with a huge pelvic mass with postmenopausal b...

this study was performed to determine the incidence and anatomo-pathological aspects of the reproductive system tumors in commercial laying hens. post mortem examination of 1041 laying hens revealed neoplasms of the ovaries and the oviduct in 52 (4.99%) cases. from these, ovarian adenocarcinoma was found in 14 cases, granulosa cell tumor in 7 cases, theca cell tumor in 1 case and marek's diseas...

Introduction: Ovarian granulosa tumors are malignant belonging to the group of sexual cord and stromal tumors. Two histological forms distinguished: a form adult which is most common, much rarer juvenile form. Case Report: Our study retrospective concerned 25 cases ovarian tumor, collected at Mohammed VI center for treatment gynecological mammary cancers Ibn Rochd University Hospital in Casabla...
