A case of primary @entity1466 in the pineal region is reported. A six-year-old @entity1 showing precocious puberty, suddenly developed @entity772 by massive @entity548 . He recovered gradually up to @entity2845 mutism, but whose clinical, hormonal and neuroradiological studies failed to demonstrate any pathological lesions. Four years later a small @entity5 was detected by CT in the pineal region. At the same time increased serum- @entity6740 level was shown. @entity5 was carried out by Stein's supracerebellar infratentorial approach. The pathology of the @entity5 showed the characteristics of @entity1466 , consisting of major @entity39 area and of @entity5 cells, syncytiotrophoblast and cellular trophoblast. The former revealed strong activity of @entity6740 by immunoperoxidase study. Postoperative chemotherapy with @entity4316 and @entity1499 was given for a month. In the course of these treatments, serum- @entity6740 recovered within normal range. This @entity1 shows no signs and symptoms of the recurrence 6 months after operation. Early diagnosis with aids of neuroradiology as well as hormonal studies and the early initiation of the treatment may prevent major complications like massive @entity5 , also might achieve the favorable outcome of this @entity5 .
