Trophoblastic Pseudotumour of the Uterus

Abstract
A 52-yr-old women with vaginal bleeding and a hysterectomy because curettings prompted suspicion of malignancy. A uterine tumor with deep infiltration of trophoblastic cells in the myometrium was revealed. Postoperative quantitative analysis for urinary human chorionic gonadotropin gave 1500 IU/1. The patient got no other treatment and is well 3 yr after operation. The histopathological picture and clinical course were consistent with the recently introduced diagnosis of benign trophoblastic pseudotumor, which should perhaps replace the old terms syncytioma and chorionepitheliosis.
