title: Myxoid chondrosarcoma in the pineal region.
abstract: The authors report a case of a myxoid chondrosarcoma of the pineal region in a 37-year-old woman who presented with an intratumoral hemorrhage. Partial removal of the tumor in an initial surgery resulted in failure to establish a definitive diagnosis. The residual tumor enlarged after a second intratumoral hemorrhage 14 months after the onset of the first symptoms, and gross-total resection of the tumor was achieved in a second surgery. Histological and immunohistochemical findings after the second surgery were consistent with a diagnosis of myxoid chondrosarcoma. Radical excision of a tumor was considered to play an important role in the management of intracranial myxoid chondrosarcoma.
