Over these years, more and more sex cord-stromal tumors have been reported. Granulosa cell tumor (GCT) is a rare tumor in ovaries, accounts for 2% to 5% of ovarian cancers. The main different feature of GCTs from other ovarian cancers is that GCTs can lead to abnormally secreted hormones (estrogen, inhibin and Müllerian inhibiting substance). The GCT is divided into two categories according to ...
We used co-cultures of porcine ovarian granulosa cells and mouse adrenocortical tumor cells (Y-1) to examine the kinetics of contact-dependent intercellular signal transfer and to assess the molecular mechanisms employed by this process. Exposure to follicle-stimulating hormone (FSH) caused cAMP-dependent protein kinase dissociation in granulosa cells and, with time, in Y-1 cells if, and only i...
Pelvic ultrasound scanning in asymptomatic adult-type granulosa cell tumor: A case report and review
Background: Ovarian cancer is common amongst women worldwide. In Indonesia, it the fourth most female with a 5-year survival rate of 45%, but can reach up to 92% if treated early. Granulosa cell tumors (GCT) arise from sex-cord and are considered malignant. This study presents rare case asymptomatic adult-type granulosa tumor in an elderly lady diagnosed during routine pelvic ultrasound scannin...
OBJECTIVE To describe the short- and long-term survival rates in horses undergoing ovariectomy for granulosa cell tumors by use of the diagonal paramedian approach. DESIGN Retrospective case study. ANIMALS 12 horses with granulosa cell tumors. PROCEDURE A diagonal paramedian approach for unilateral ovariectomy was used for removal of each mare's granulosa cell tumor. Information about com...
We established a steroidogenic human ovarian granulosa-like tumor cell line, designated KGN, from a patient with invasive ovarian granulosa cell carcinoma. KGN had a relatively long population doubling time of about 46.4 h and had an abnormal karyotype of 45,XX, 7q-, -22. A steroid analysis of the cultured medium by RIA performed 5 yr after the initiation of culture showed that KGN was able to ...
The ovary is itself a hormone secreting organ, and it has been shown that some ovarian tumors also secrete hormones. Granulosa cell tumors and theca cell tumors are hormone secreting tumors. There have been many reports on the histogeneses, character, and nomenclatures of these tumors. In 1944, Biskind et al. reported the development of granulosa cell tumors and luteoma by intrasplenic ovarian ...
Granulosa cell tumors is classified into juvenile and adult types and comprise less than 5% of ovarian tumors in women and are much rarer in men which only 45 have been previously reported. We report here a 40-year young man with a left testicular adult type granulosa cell tumor. The tumor measured 5.5X5X4cm; Immunohistochemical stains showed the tumor diffusely positive for inhibin and vimenti...
