UTERUS - Carcinoma

A uterus, opened to show a polypoid tumour mass 3.5 x 2 cm., with no obvious invasion of the myometrium. There is a fibroid just under 1 cm. in diameter in the uterine wall, and there are several cystic areas in the lower part of the endometrial canal.
This woman presented with a post-menopausal bleeding, and biopsy showed a well-differentiated adenocarcinoma. The histology of the lesion shown here is a well-differentiated adenocarcinoma arising from relatively narrow base, and showing little myometrial infiltration.
