Trophoblastic pseudotumour of the uterus. A case report

A 52-year-old woman with vaginal bleedings had hysterectomy because curettings prompted suspicion of malignancy. A uterine tumour with deep infiltration of trophoblastic cells in the myometrium was revealed. Postoperative quantitative analysis for urinary human choriongonadotropin gave 1500 IU/1. The patient got no other treatment and is well 3 years after operation. The histopathological picture and the clinical course were consistent with the recently introduced diagnosis of benign "trophoblastic pseudotumour", which should perhaps replace the old terms "syncytioma" and "chorionepitheliosis".
