Ultrastructure of a granulosa cell tumor
American Journal of Obstetrics and Gynecology, 1968Abstract Ultrastructural investigation of an ovarian granulosa cell tumor has revealed structural traits conforming to those of the normal, nonluteinized granulosa cell. Cytoplasmic membranous systems and mitochondria were well developed. Lipid inclusions were numerous. Nuclei demonstrated some degree of pleomorphism, and nucleoli were prominent. The

Granulosa cell tumours of the ovary
Australian and New Zealand Journal of Obstetrics and Gynaecology, 2010Granulosa cell tumours are rare, potentially malignant sex cord stromal tumours of the ovary. They are unique in their presentation and histological features. Many of them are hormone‐producing and this property helps them to present early unlike other epithelial ovarian cancers.

Extraovarian Granulosa Cell Tumor
Gynecologic Oncology, 1999The aim of this study was to report a case of extraovarian granulosa cell tumor and to describe its relevance to the histologic origin of granulosa cell tumors and to clinical practice.The clinical course and histopathology of the case were reviewed, and a literature search for other reported cases was performed.A 67-year-old woman presented with ...

Granulosa-cell tumor of the ovary
American Journal of Obstetrics and Gynecology, 1946Abstract A case of granulosa-cell tumor of the cylindromatous type has been reported. The patient, a 55-year-old woman, had clinical symptoms and physical findings sufficiently characteristic to suggest the diagnosis preoperatively. A brief consideration of the incidence, histogenesis, and pathology has been presented.

Inhibin as a Marker for Granulosa-Cell Tumors
New England Journal of Medicine, 1989Inhibin is a peptide hormone normally produced by ovarian granulosa cells. It reaches a peak of 772 +/- 38 U per liter in the follicular phase of the menstrual cycle and is undetectable in the serum of menopausal women. To determine whether measurements of serum inhibin levels would provide a biochemical marker of the presence or progression of ovarian

Ovarian Stimulation and Granulosa-Cell Tumour
Obstetrical & Gynecological Survey, 1993Ovarian stimulation in the treatment of infertility is far from physiological because patients and their ovaries are exposed to high concentrations of gonadotropins. Many studies have focused on the two most common side-effects of ovarian stimulation--ie, hyperstimulation and multiple pregnancy. We describe 12 patients in whom granulosa-cell tumour was

Bioencapsulation of Oocytes and Granulosa Cells
2018A protocol for the encapsulation in sodium alginate of granulosa cells in primary culture and co-culture of oocyte-cumulus complexes is reported. Sodium alginate forms strong gels when jellified with barium ions, allowing the self-organization of cells into a 3D structure.

Granulosa cell tumor in a goat
Journal of the American Veterinary Medical Association, 1986Granulosa cell tumors are rare in the goat. This report deals with the shortened estrous cycles, masculinization, depressed fertility, and the systemic hormone profiles resulting from a granulosa cell tumor in a doe. Data are supported by unique information on the steroid content of the tumor.

Displaced Granulosa Cells in the Fallopian Tube Mistaken for Metastatic Granulosa Cell Tumor
International Journal of Gynecological Pathology, 2013A 44-yr-old woman underwent a total hysterectomy and bilateral salpingectomy secondary to uterine leiomyomas. Gross examination of the fallopian tubes revealed no masses or lesions; however, 2 small foci of granulosa cells were identified microscopically within one of the fallopian tubes.

Fertility and Sterility, 1996
To determine if embryos can modulate steroid hormone production by luteinized granulosa cells.Granulosa cells obtained from follicular aspirates were cultured alone or in the presence of a two-pronuclear zygote. The production of E2 and P by these cultures was evaluated by RIA.In Vitro Fertilization Unit in an academic research environment.Sixteen ...
