ABSTRACT
Dermal melanocytosis includes a variety of congenital and acquired conditions characterized by a sparse population of intradermal dendritic, variably pigmented, spindle-shaped melanocytes. Mongolian spot, Ota's and Ito's nevi are usually present at birth or appear in early childhood. But, several types of acquired dermal melanocytosis that usually appear in adults have been reported. A 47-year-old woman presented with asymptomatic, multiple, symmetric, brownish to black colored macules on the nasal ala, both palms and both feet dorsum that had been there for 10 years. Histopathologic findings showed that some scattered spindle-shaped cells containing melanin pigment in the upper dermis were positive for Fontana-Masson stain and these cells were positive for S-100 protein and MART-1.
