Abstract
- Dermal melanocytosis is histologically characterized by the presence of ectopic melanocytes in the dermis. Mongolian spots, nevus of Ota, nevus of Ito and blue nevus are the most common types and these are usually present at birth or in early childhood. However, it has been reported that several types of dermal melanocytosis could appear in adult life. We report here on an unusual case of acquired dermal melanocytosis occurring in a 51 year-old female. She had bilaterall brownish or slate-bluish pigmented patches on the face and the posterior auricular, supraclavicular, scapular and back areas. The skin biopsy specimen taken from the upper back revealed scattered, darkly pigmented, spindle-shaped cells and dendritic cells containing abundant golden brown pigment in the dermis.
