The differential diagnosis of endometrial adenocarcinoma. Some viewpoints concerning a common diagnostic problem

Histological criteria which we have found useful for diagnosing endometrial adenocarcinoma are presented and guidelines are developed for separating adenocarcinoma from benign proliferations which can mimic carcinoma, including endometrial hyperplasia with atypia, endometrial epithelial metaplasias, secretory endometria and disintegrating endometrium. The problem of distinguishing endometrial adenocarcinoma from other malignancies is also discussed.
