Melanotic medulloblastoma of cerebellum: a case report.

A case of 7 yr old boy with cerebellar melanotic medulloblastoma is reported. Melanotic medulloblastoma is a variant of medulloblastoma, which shares some of the histological features of Melanotic neuroectodermal tumor of infancy. However the predominant histological pattern and clinical behavior is that of conventional or classical medulloblastoma. The melanin pigments present in these tumors have been proved to be both neuromelanin and oculocutaneous type of melanin. This is a rare histological type and only few cases have been reported in the literature so far.
