@entity320 is usually black in color because of the existence of melanin pigments in it. Differing from such a @entity320 , @entity5701 , which has no melanin pigments and is not black-colored, is rarely described in literature. In this report, a case of @entity5701 of unknown origin is presented and discussed. This represents the seventh case report of an @entity5701 . On May 28, 1984, a 55-year-old @entity1 was admitted to our department because of repeated left hemiconvulsion. Neurological and physical examination disclosed left @entity1269 , poor concentration and right inguinal @entity5 . CT scan revealed a right posterior frontal mass with ring like enhancement. On June 7, the @entity1 underwent craniotomy. The @entity1313 , partly emerged from right frontal lobe, was reddish and easy to bleed. Macroscopically there were no abnormal findings over leptomeniges. The right inguial @entity5 , that were lymph nodes, were also removed simultaneously. Microscopic interpretation at that time was that of a @entity5 of ectodermal origin. Although no melanin pigments were demonstrated in any specimens except for a part of lymph nodes, dopa reaction was positive in both specimens from the @entity1313 and the inguial lymph nodes, strongly suggesting @entity5701 . Postoperative course was uneventful, but CT scan of Aug. 31 again showed multiple intracerebral enhanced lesion and @entity548 . @entity2026 , right @entity1269 and consciousness disturbance developed gradually, and he died on Sept. 21, 1984. Autopsy demonstrated multiple intracerebral @entity1410 , containing much @entity5 cells in lung, thyroid and subcutaneous tissue. @entity75 remained unknown in spite of an extensive examination in autopsy.(ABSTRACT TRUNCATED AT 250 WORDS)
