granular cell tumor/progesterone

Granular cell tumors occur in a variety of sites, including the breast (6%). Origins from histiocytic, myogenic, fibroblastic, and neurogenic elements have been proposed. Female predominance suggests that estrogenic hormones are involved. Four granular cell tumors of the breast and one in an

The authors report a case of a gingival granular cell tumor, also called "congenital epulis", occurring in a female newborn. It is a rare congenital, benign tumor of uncertain histogenesis, with marked predilection for female newborn. The tumor arises, as a polypoid mass, on the gingiva of the

Report about a 46 year old women with granular cell tumor of the breast. Clinical features, mammography and sonography has appearances highly suspicious for breast cancer. Tumorectomy and axillary lymphonodectomy were performed. Estrogen and progesterone receptor both were histochemically and

Non-neural granular cell tumors (GCTs) are clinically rare, whereas cases arising in the uterine corpus are exceedingly rare. Only three uterine cervical cases of GCTs have been reported to date and, to the best of our knowledge, there are no reports of GCT of the uterine corpus in the literature.

BACKGROUND Granular cell tumor (GCT) is a rare variant of mammary tumor beset with diagnostic dilemmas that may be resolved by using numerous, very complex, enzymohistochemical and immunohistochemical methods. METHODS We reported three female patients 16, 21 and 65 years old, operated on for mammary

Gingival granular cell tumor of the newborn, or congenital epulis, is a rare congenital lesion of uncertain histogenesis located exclusively on the alveolar ridge with marked predilection for female infants. Although histologically similar to the more ubiquitous granular cell tumor or myoblastoma,

OBJECTIVE Granular cell tumor (GCT) is a rare neoplasm that can appear in any site of the body, but most are located intraorally. Its histogenetic origin remains unclear. This report analyzes the immunoprofile of 15 cases of granular cell tumors, occurring in 13 women and 2 men and the lesions were

We describe the first case of a granular cell tumor of the thyroid. The tumor appeared while a girl was receiving high-dose estrogen therapy for tall stature. The tumor, however, did not contain estrogen or progesterone receptors. Although granular cell tumors occur twice as commonly in women as in

We report a case of 49 year old woman with metastasizing granulosa cell tumor of the ovary, adult type, to the right adrenal gland 13 years after initial diagnosis. The tumor was asymptomatic and was detected incidentally by ultrasonography. We performed histopathological analysis of the tumor using

Epulis is a rare tumor of the newborn, also known as granular cell tumor of the newborn or Neumann's tumor. This tumor arises from the mucosa of the gingiva, most commonly from the anterior part of the maxillary alveolar ridge, and is typically seen as a mass protruding out of the newborn child's
