title: Primary meningeal melanocytoma of the pineal region. Case report.
abstract: A unique case of a meningeal melanocytoma located in the pineal region is presented. This 48-year-old man presented with a round pineal region tumor that caused triventricular hydrocephalus and exhibited slow clinical progression. During surgery a black encapsulated tumor was found and totally removed. On histopathological examination, the tumor proved to be a meningeal melanocytoma. In this report cell culture data are presented and the relevant literature is reviewed. The problems of histopathological diagnosis and management of patients with melanocytomas are also discussed.
