[Histological and diagnostic criteria and incidence of endometritis in abrasion material].

At present the diagnosis "endometritis" is diagnosed too frequently by the histological examination of the endometrial biopsies. An essential cause is the misconstruction of cells of the endometrial stroma. This investigation is based on the histological diagnosis of 3729 endometrial biopsies. 229 cases represent changes of the endometrium after pregnancy (abortion, birth). Among 3500 endometrial biopsies 9 cases (=0,3%) had been diagnosed as "nonspecific chronic endometritis". The histological signs of the endometritis are described.
