RESUMEN
Objectives:To determine the expressions of decoy receptors (DcR1 and DcR2) of TRAIL in carcinoma of endometrium. Methods:The expressions of DcR1 and DcR2 in endometrium tissues from 13 carcinoma of endometrium and 7 normal endometrium were detected by immunohistochemical staining.Results: The expressions of DcR1 and DcR2 in carcinoma of endometrium were much lower than in normal endometrium. Conclusions:The decreasing of DcR1 and DcR2 in carcinoma of endometrium may be concerned with its pathogenesis, which may be related to the prevention of endometrium from carcinomatous change.
RESUMEN
Clear cell carcinoma of the endometrium is a relatively rare malignancy that is considered to be one of the most aggressive types of endometrial carcinoma. It is an infrequent variant sharing a common Mullerian origin, accounting for 1 to 5 percent of all endometrial cancers. Histologically, these tumors consists of hobnail cells which have translucent or slightly eosinophilic cytoplasm and protrude to lumen of gland. These tumors occur predominantly in postmenopausal women and carry a relatively unfavorable prognosis comparing with other histologic types of endometrial cancer. We experienced a case of clear cell carcinoma of endometrium in a 81-year old women and this case is presented with a brief review of the literaturs.
