We present a case of a 25-year-old patient at term pregnancy who presented with a bilateral ovarian neoplasm that was histologically and immunohistochemically indistinguishable from ependymoma of the central nervous system. Progesterone receptors were detected in primary and recurrent neoplasms by

Ovarian ependymomas are extremely rare tumors of the ovary. We present a case of a 67-year-old lady presented to us with swelling in the right side of neck for 2 months followed by pelvic pain, lower abdominal distention, and weight loss for 1 month. Her coagulation profile, blood chemistry, lipid

Ependymomas of the central nervous system and adult extra-axial ependymomas are morphologically and immunohistochemically distinct--a comparative study with assessment of ovarian carcinomas for expression of glial fibrillary acidic protein.

Extra-axial ependymomas are very rare but have been reported in the ovary, broad ligament, sacrococcygeal region, lung, and mediastinum. The histogenesis is obscure, and a thorough immunohistochemical analysis is lacking. We reviewed the morphologic and immunohistochemical features of 5 extra-axial

Ovarian ependymomas of extra-axial type or central immunophenotypes.

We report the differential clinicopathologic and immunophenotypical features of 2 pure ovarian ependymomas of extra-axial type with a predominant microcystic, anaplastic pattern occurring in patients aged 22 and 32 years and a unique myxopapillary pigmented ependymoma that originated within an

OBJECTIVE Ovarian anaplastic ependymoma is a rare gynecologic malignancy that poses diagnostic and treatment challenges. Treatment of sub-optimally debulked disease usually portends poor prognosis. Molecular testing of tumor specimen can identify more specific targets for additional therapy such as

BACKGROUND Histopathologic diagnosis and treatment of ovarian anaplastic ependymoma are challenging. METHODS A 61-year-old-woman presented with a 10-cm right adnexal tumor associated with peritoneal carcinomatosis extending to the right diaphragm and liver surface. After initial diagnosis of a

Immunostaining of progesterone receptors (PRs) has been described as a prognostic factor related to recurrences in meningiomas. However, its expression in other primary intracranial tumors has been poorly studied. In this paper, we compare the pattern of expression of the receptor in meningiomas

OBJECTIVE To report an exceptional case of papillary ependymoma occurring in the endometrium. RESULTS A clinicopathological study was performed regarding a case of papillary ependymoma occurring in the endometrial cavity of a 61-year-old patient who had presented with a solid-type, stage III

To the best of our knowledge, there are currently no reports on primary uterine ependymoma. We operated on a 38-year-old woman suspected with uterine fibroids; surgical findings led to the diagnosis of primary anaplastic ependymoma of the uterus. Most extraneural ependymomas arising from the ovary

Extraspinal ependymoma is a rare tumor, occurring most commonly in the sacrococcygeal region, and only a small number of cases have been reported to arise in the uterine ligament. Herein is reported a case of extraspinal ependymoma arising in the broad ligament of a 27-year-old woman. The lesion was

To investigate the role of steroid hormones in the occurrence and growth of human spinal cord tumors and to study the biochemical basis of the sex related difference in the incidence of the various spinal oncotypes, ER and PR have been measured in 24 human spinal cord tumors (12 neurinomas, 6

Primary glial and neuronal tumors of the ovary or peritoneum are rare neuroectodermal-type tumors similar to their counterparts in the central nervous system. We retrospectively reviewed 11 cases. These cases included 4 ependymomas, 6 astrocytic tumors, and 1 neurocytoma. Patients' age ranged from 9

The March COM. A 41-year-old woman presented in 1997 with diffuse abdominal pain, meteorism and intermittent diarrhea. Imaging studies revealed a focal rounded lesion in the liver. Although there was no history of progesterone or estrogen therapy, the radiographic appearance was considered to be

The effect of prolactin and bombesin on the growth of meningioma-derived cells in monolayer culture.

Meningioma growth is thought to be stimulated by the sex hormones progesterone and possibly estrogen. We report here stimulation of growth of meningioma-derived cells in culture by prolactin. Fourteen human tumors taken from surgery were initially grown in Ham's medium F10 with 15% fetal calf serum.
