Mullerian adenosarcoma with ovarian sex cord-like differentiation. A light- and electron-microscopic study

Abstract

A Müllerian adenosarcoma in which the sarcomatous element showed ovarian sex-cord like differentiation, occurred as a polypoid growth in the uterine cervix of a 53-year-old woman. The tumor was composed of an admixture of benign neoplastic glands and a sarcomatous stroma, the latter containing in addition to endometrial stromal sarcoma, nests of lipid-rich cells resembling ovarian sex-cord elements. This is the first report of such differentiation in Müllerian adenosarcoma. Origin from a focus of cervical endometriosis is postulated.
