Abstract:
We report 4 cases of intracranial melanoma without any clinically diagnosed extracerebral location. These tumors presented at different sites and had different histological aspects. Intracytoplasmic melanin was present in all cases, immunohistochemistry confirmed the diagnosis and eliminated a possible glioblastoma or metastatic carcinoma. Clinical and pathologic characteristics of primary pigmented lesions of the CNS are discussed with particular interest in diagnostic difficulties and histogenesis of these lesions.
