Abstract
Neurocutaneous melanosis (NCM) is a rare phakomatosis with focal or diffuse proliferation of melanin-producing cells in both the skin and the leptomeninges. Two-thirds of the affected subjects present giant congenital melanocytic nevi and the remaining third numerous melanocytic nevi in the absence of single giant skin lesions. Though normal neurological development can be observed in the first months after birth, most of the patients present neurological manifestations early in life secondary to intracranial hemorrhages, accumulations of melanocytic cells in various districts of the intracranial spaces, impairment of cerebrospinal fluid circulation leading to acute hydrocephalus, and subdural fluid collections. However, malignant transformation of the melanocytes is thought to account for the early demise which characterizes the syndrome. Even in the absence of malignancy, the overall prognosis of NCM is quite poor due to the persisting unavailability of an effective treatment.
