Abstract

Recognition of the features of gestational endometrium, trophoblast, and villi, as well as the pathologic changes in chorionic tissues, is an important part of endometrial biopsy interpretation. Correct identification of gestational endometrium and placental tissue is important for several reasons. First, the presence of intrauterine products of conception generally excludes the diagnosis of ectopic pregnancy. Second, normal trophoblastic cells can appear atypical and even neoplastic, since they are primitive and highly proliferative. Third, identification of products of conception can help explain other pathologic states such as abnormal bleeding or chronic endometritis.
