Papillary metaplasia of the endometrium: clinical and histopathologic considerations

The clinical presentation and histopathology of three cases of papillary metaplasia of the endometrium are reported. This lesion is usually found with unopposed estrogen stimulation. Two of these patients were perimenopausal, and one was postmenopausal. In two of these patients chronic endometritis was found. Papillary metaplasia of the endometrium is infrequently cited and must be recognized as a benign entity.
