[Papillary adenofibroma of the uterus: fact or fancy? (author's transl)]].

This report deals with the morphological findings in the uterus of a 40 yrs old premenopausal woman, who complained of vaginal bleedings. Macroscopical and microscopical examinations revealed a hernia-like prolaps of a part of the wall of the tuba uterina across a hole in the myometrium of the fundus uteri. Vellios et al. (1973) describe a similar lesion but without paying attention to the prolaps of the tuba uterina into the cavum uteri. They interpretate the lesion as a papillary adenofibroma of the uterus and believe it to be the benign counterpart of the mixed mesodermal tumor of Müllerian duct origin. Based upon our histological findings we believe in a dysontogenetic or traumatic etiology of this rare lesion. The diagnosis of a papillary adenofibroma of the uterus therefore should only be made when the uterus and the adnexa in toto are available for histological examinations.
