Endometrioid carcinoma of the ovary

Abstract 1.1. The results of a histological review of 120 cases of primary cancer of the ovary indicates that there exists a primary adenocarcinoma of the ovary of relatively high incidence which structurally resembles adenocarcinoma of the endometrium. 2.2. Certain morphological and biological characteristics seem to support the contention that this is a distinct type of ovarian tumor. 3.3. The possibilities that this tumor is derived from benign endometriosis and that in contrast to other malignant tumors of the ovary it provides a relatively favorable prognosis are pointed out.
