[Development of endometrial cancer in one half of a double uterus].

Two observations (patients of 52- and 48-years old) in which endometrial carcinoma developed in one half of a double uterus. Tumours were highly differentiated and completely replaced a left half of the uterus. The endometrium of the right half was with no change. 52-year--old patients had endometrioid carcinoma of the right ovary as well.
