Primary melanocytic tumours of the central nervous system (CNS) form a rare entity which is histologically and clinically distinct from metastatic cutaneous or retinal malignant melanoma. They can be classified into diffuse melanocytosis (diffuse melanosis), malignant melanoma and benign melanocytoma with a small number of intermediate variants. In this paper, 5 cases treated neurosurgically in our department for spinal or cerebral primary CNS malignant melanoma are reported. Primary tumors and further metastases were ruled out. Radiological, histological and clinical features are discussed. Compared to metastatic disease, primary CNS malignant melanoma shows a more benign clinical course with long-term tumour control and a good quality of life. A review of the literature which mainly consists of individual case reports, confirms this assessment. Although therapeutic experience for primary melanocytic lesions of the CNS is based on a small number of published cases, prognosis seems highly dependent on complete tumour resection. Adjuvant radiation seems to be of additional therapeutic benefit. Except for meningeosis melanomatosa chemotherapy must be regarded as experimental. Unfortunately, a standardised therapy concept is still lacking.
