Abstract:
A 36-year-old man presented with a giant congenital melanocytic nevus and multiple disseminated melanocytic nevi. After he had developed neurological symptoms (grand mal seizures), a cerebral metastasis of a malignant melanoma without a primary melanoma was found. The patient was diagnosed as having a neurocutaneous melanosis with a cerebral metastasis. In spite of a variety of therapeutic attempts (surgery, radiation therapy and chemotherapy) he followed a rapidly progressive, lethal course with increased intracranial pressure, hydrocephalus and spinal metastases.
