title: [Spinal and cerebral leptomeningeal seeding from a melanocytoma of the cerebello-pontine angle].
abstract: Meningeal melanocytoma refers to the uncommon clinical appearance of a generally benign tumour deriving from leptomeningeal melanocytes. Meningeal spread of this tumour is very rarely observed. We present the case of a 38-year-old man with meningeal melanocytoma of the cerebello-pontine angle, who showed a biphasic course of this disease, with a stable period followed by a steady progress within few months. After surgical resection of the melancytoma in the left skull base and of a first local recurrence five years later, a second local recurrence occurred 6 years after diagnosis, with intracerebral and spinal meningeal seeding. This tumor did not respond to a combined radiochemotherapy including oral temozolomide, and the patient died 5 months after starting treatment for this relapse. Secondary malignisation of the melancytoma is suggested.
