Genetic and Rare Diseases Information Center (GARD) - PO Box , Gaithersburg, MD - Toll-free:   These tumors are named for the particular ovarian cells that are involved–granulosa and theca cells. This type of ovarian tumor is by far the most common in the horse. Luckily, these tumors .

Granulosa cell tumor. Granulosa cell tumor (q.v.) is the most common ovarian neoplasm in the mare. One of the first palpable changes is an enlarged ovary with loss of the ovulation fossa. Steroid hormones and/or inhibin produced by the tumor have an inhibitory feedback on the hypothalamus and pituitary.   Granulosa theca cell tumours represent the largest group of hormone-secreting ovarian tumours and comprise approximately % of all ovarian malignancy. However, the prognosis and behaviour of pure granulosa cell tumours have been particularly difficult to evaluate, because in previous reports they have been grouped with granulosa theca cell.

Continued Ovarian Stromal Tumors. These types of tumors are often diagnosed earlier than others. The most common subtypes are granulosa-theca tumors and Sertoli-Leydig cell are rare. Ovarian granulosa cell tumors (GCT) are rare and comprise only 2–5% of the approximat cases of ovarian cancer diagnosed each year in the United States [1 x [1] Schumer, S. and Cannistra, S.A.

Granulosa cell tumours are tumours that arise from granulosa are esterogen secreting tumors and present as large, complex, ovarian masses. These tumours are part of the sex cord-gonadal stromal tumour or non-epithelial group of tumours. Although granulosa cells normally occur only in the ovary, granulosa cell tumours occur in both ovaries and testicles (see Ovarian cancer and Specialty: Gynecologic oncology, obstetrics and.

Introduction Granulosa theca cell tumors (GTCT) are the most common ovarian tumor in mares (% of all equine neoplasia). Originate from sex cord stromal tissue and are usually benign. Cause: proliferation of granulosa cells due to dysregulation of several pathways associated with FSH receptors.

Objective: Our purpose was to review patients with granulosa and theca cell tumors as filed in the Emil Novak Ovarian Tumor Design: Our study was a descriptive, retrospective study of case s: The reviewed diagnoses were for 97 patients with granulosa cell tumors, with theca cell tumors, and 97 with granulosa-theca cell by:   Granulosa-theca cell tumors, more commonly known as granulosa cell tumors (GCTs), belong to the sex cord–stromal category and include tumors composed of granulosa cells, theca cells, and.

Granulosa theca cell tumors are more commonly referred to as granulosa cell tumors in cattle. Overall, neoplasia in cattle is uncommon, however the granulosa cell tumor is the most commonly reported type of ovarian tumor in cattle; Cause: proliferation of granulosa cells due to dysregulation of several pathways associated with FSH receptors.

J Obstet Gynaecol Can. Apr. 27(4) Natural history of granulosa cell tumors of the ovary. Granulosa cell tumors (GCTs) of the ovary are relatively uncommon neoplasms, representing approximately 5 to 10% of all ovarian malignancies [1,2]; the others are germ cell tumors (teratomas and yolk sac tumors, 60 to 70%) and epithelial adenomas (10 to 20%) [].GCTs of the ovary belong to the group of ovarian sex-cord stromal tumors.

OVARIAN TUMOURS: ETIOPATHOGENESIS. Not much Is known about the etiology, few risk factors have been identified Granulosa- Theca cell tumors: Granulosa cell tumors, Thecoma-fibroma group; (Ovarian Tumor) Rare group of tumors, the most common of which are struma ovarii and carcinoid.

Unilateral tumors. Diane DeFriend, in Clinical Ultrasound (Third Edition), Granulosa cell tumours. Granulosa cell tumours are rare, accounting for 3% of all ovarian malignancies, but are the most common malignant sex cord stromal tumour. They include adult granulosa cell and juvenile granulosa cell tumours, with only the former discussed here.

All studies describing the effect of hormone therapy in individual patients with measurable GCT, gynandroblastoma and granulosa theca cell tumors were eligible. The design or number of reported patients was no exclusion criteria, because of the scarcity of data available from large, prospective, randomized trials on this rare tumor.

Granulosa cell tumours (GCT or sex cord-stromal tumours) are the most common ovarian tumour in horses and can occur in mares of any age. They may be composed of granulosa cells alone or contain theca cells (granulosa-theca cell tumours).

They are almost always unilateral, functional and benign. The prognosis for granulosa-theca cell tumors generally is very favorable. GCTs are considered to be tumors of low malignant potential.

Approximately 90% of GCTs are at stage I at the time of. Granulosa cell tumors (GCTs) of the ovary comprise 2 to 5% of malignant ovarian tumors [1,2], and 20 to 30% show malignant clinical and histopathological characteristics.

The clinical outcome for tumors at stages I and II is excellent, whereas those at stages III and IV remains poor. Granulosa cell tumors (GCTs) are rare functional sex-cord-stromal ovarian neoplasms characterized by low malignancy potential and late relapse, which rarely metastasize to the liver.A year-old female, who had undergone surgery to treat a GCT of the.

Granulosa cell tumors (GCTs) of the ovary arise from the cells that would typically give rise to specialized gonadal stroma surrounding the oocytes.

They are the most common type of malignant sex cord stromal tumor (SCST), comprising 2–5% of all ovarian malignancies. WITHIN RECENT years granulosa-theca-cell tumors have attracted much interest, primarily because of their hormonal function.

These tumors are the principal feminizing neoplasms of the ovary; and it has been emphasized that when they occur in prepubertal females, they almost always cause sexual precocity. Granulosa-Theca Cell Tumors in the Mare Granulosa-theca cell tumors (GCT’s) represent the most common group of tumors that develop in the equine ovary and probably comprise % of all equine tumors.

These tumors have been reported in all ages and breeds, even in pregnant mares, but are most common in five- to ten-year-old mares. Granulosa cell tumor of the ovary is a rare type of ovarian cancer that accounts for approximately 2% of all ovarian tumors. This type of tumor is known as a sex cord-stromal tumor and usually occurs in adults.

Granulosa cell tumors of the ovary cause higher than normal levels of estrogen in a woman's body. The symptoms of this excess estrogen depend on the woman's menstrual status; .Sex cord-stromal tumors are derived from the granulosa, theca, and/or stromal fibroblast components of the ovary and represent ~8% of all categories of ovarian tumors [1].
