brenner tumor/プロゲステロン

A case of a malignant Brenner tumor of a postmenopausal woman presenting with vaginal bleedings is described. Clinical and laboratory findings demonstrated estrogenic secretory function and action. The presence of aromatase activity based on in vitro tumor microsomal metabolism of androgen to

Brenner tumor is a rare ovarian neoplasm that is seen in women of the fifth to sixth decade. Classified as benign, borderline, and malignant, these tumors may be associated with estrogen production, thus altering the estrogen-progesterone ratio. High estrogen stimulates the endometrium and this is

Brenner tumor is a rare ovarian neoplasm which is generally monolateral, more rarely bilateral, and often associated with endometrial disorders related to oestrogenic production. However, there is no considerable evidence that the possible oestrogenic production of this tumor may be the cause of

Aromatization is the biochemical process in which aromatase catalyzes the conversion of testosterone into estradiol, the fundamental pathway for the synthesis of estrogens. When enhanced, it can lead to hyperestrogenism, a well-known risk factor for gynecological cancers. The surgical specimens,

We report 10 cases of a morphologically distinct vaginal polyp which has hitherto not been characterized. The polyps occurred in women aged 39 to 78 years (most were postmenopausal) and were from 1.0 to 3.0 cm. Most of whose location is known to us were in the upper vagina. Histologically, all the

Brenner tumors of ovary are usually an incidental finding. It is an uncommon tumor which is seen affecting women of fifth to sixth decade. It is classified under transitional cell tumors of ovary, which includes benign, borderline, and malignant Brenner tumors and transitional cell carcinoma. These

BACKGROUND Leiomyomatosis peritonealis disseminata has been attributed to estrogen stimulation and is seen only rarely in postmenopausal women. In such cases, pathogenesis is uncertain. METHODS Leiomyomatosis peritonealis disseminata tumors were resected from a postmenopausal woman. She was
