title: [A case report of germinoma with syncytiotrophoblastic giant cells (STGC) in the basal ganglia].
abstract: We report a case of germinoma with syncytiotrophoblastic giant cells (STGC) in the basal ganglia which was encountered at the Department of Neurosurgery, Hiratsuka City Hospital, Kanagawa, Japan. A 9-year-old boy was admitted to our hospital on September 13th, 1993 because of left hemiparesis and precocious puberty. Endocrinological examination revealed a high serum level of human chorionic gonadotropin (HCG) (290 mIU/ml) and beta-subunit human chorionic gonadotropin (HCG-beta) (1.3 ng/ml). Plain CT scan showed an irregularly-defined mass lesion in the right basal ganglia, which had several low density spots and was inhomogeneously enhanced on contrast CT scan. The tumor developed from the right putamen to the thalamus and showed a tendency towards involvement of the hypothalamic region on MR imaging. We performed a right front-temporal craniotomy on 29th September, 1993, and a piece of the tumor was removed. It was histologically diagnosed to be germinoma with STGC. We treated the patient with carboplatin and etoposide (CBDCA 200 mg/m2day1, VP-16 60 mg/m2day1-5) chemotherapy and radiotherapy (local 30 Gy) after surgery. Postoperative course was good without recurrent signs. He is now in good health and going to elementary school without neurological deficit. There are very few reports of germinoma with STGC arising in the basal ganglia. We provide a new treatment of germinoma with STGC, chemotherapy and radiotherapy after surgery.
