A 22 year-old male patient had a choriocarcinoma of the mediastinum metastatic to the brain, liver, lung and skin. He was treated with five cycles of chemotherapy containing cisplatinum, vinblastine, VP16 and bleomycin and he achieved a partial remission. Then he developed a progressive disease exclusively located to the brain and he died of an intracranial hemorrhage. The autopsy showed the mediastinum and the lung being free of residual trophoblastic tumor. Pure choriocarcinoma is rare in males, but brain metastases are frequently present in this case. Therapeutic guidelines are uncertain, so they must refer to the experience obtained in gestational choriocarcinoma. Two groups of patients are individualized both in male germ cell tumors and in placental choriocarcinoma: one group of patients with brain metastases at diagnosis, with a better prognosis, and one group of patients with brain metastases occurring in the course of the disease, with a poor outcome. The risk of intratumoral hemorrhage is common to all varieties of choriocarcinoma brain metastases and is not lowered by greater effectiveness of the chemotherapy. Brain metastases found at the moment of the choriocarcinoma diagnosis require chemotherapy and radiotherapy and in some selected cases, a surgical removal.
