A case of a metastatic cerebral chorioncarcinoma in the posterior aspect of the left frontal lobe of a 19-years-old woman is reported. After neurosurgical excision of the brain tumor a retrospective study of the patient was carried out as far as the gynecologic complaints were concerned. The patient complained only of little blood loss through the genitals started some weeks after the birth of a normal child four months ago. A smear vaginal preparation showed the presence of atypical epithelial cells (class V of Papanicolau). A total hysterectomy associated with bilateral anexectomy was performed. A small hemorrhagic tumor was detected within the uterus and a histological examination showed a chorioncarcinoma invading the miometrium. The clinico-pathological aspects of the chorioncarcinoma with special emphasis to cerebral metastases are discussed.
