Primary intracranial malignant melanoma in an adolescent girl: A case report

Primary intracranial malignant melanoma is a very rare tumor, and most of the central nervous system melanomas are metastatic diseases. Diagnosis needs extensive dermatological, opthalmological, and radiological workup to exclude metastatic melanoma. Histologically, it should be differentiate from benign melanocytic lesions, pigmented choroid plexus carcinoma, and pigmented papillary medulloblastoma. Here, we are reporting a case of primary malignant melanoma of posterior fossa in an adolescent girl diagnosed in squash cytology as well as in histology and confirmed by immunohistochemistry and by excluding metastatic melanoma.
