SEGMENTAL, SPECKLED, LENTIGINOUS NEVUS

Speckled, lentiginous nevus (SLN) is a congenital pigmented lesion in which macules or papules are superimposed on a light brown background patch. Histopathologically a lentigo-like pattern is visible in the ba ckground area, while junctional or compound nevi are found in the dott ed maculopapular lesions. We describe a case of SLN localized on the r ight foot of a 57-year-old woman. The particular distribution of this lesion permits a discussion about the confusion of morphological terms used to indicate SLN or lentiginosis. Moreover we point out the probl ems about strict diagnostic criteria for SLN and the prognostic value of this lesion.
