Meningioma with Metastatic Malignant Melanoma: An Unusual Coincidence

Meningiomas are the tumors which are found in cases of multiple intracranial tumors of different histology. This is attributed to frequent occurrence of intracranial meningiomas and their long clinical evolution before diagnosis. Thus, they have an increased probability of simultaneously harboring another primary or secondary intracranial tumors. Central nervous system (CNS) melanotic tumors include the rare primary melanomas and the more common secondary melanomatous deposits.1 Melanoma ranks fourth in the incidence of brain metastases.2 We present a case which involves two separate right convexity tumors. Histopathology of the excised specimens revealed two histologically different tumors: a transitional meningioma and second metastatic melanoma. Simultaneous occurrence of meningioma and brain metastasis as two different histological proven lesions has been reported in various literature,3,4 however, to the best of our knowledge, contiguous occurrence of meningioma and malignant melanoma has not been reported previously in literature. We would like to document this as the first case.
