[Multinodular plaque-type blue nevus, superficial and neuroid].

We report an exceptional case of multinodular plaque-type blue nevus in a 63-year-old woman, located on the presternal region. The lesions appeared at the age of 25 years on an achromic area. The probable clinical diagnosis was that of a pigmentary nevus. Histopathological examination showed a partially cellular blue nevus with a superficial topography and a neuroid arrangement. On this occasion, a review of the literature and a study of this peculiar form of blue nevus are made.
