A case of plaque-type blue nevus on the scalp

Abstract

Common blue nevi are solitary, asymptomatic blue-gray, or blue-black papules, usually less than 10 mm in diameter. Rarely, lesions may be multiple and agminated or arranged in large plaques. Common blue nevi may occur anywhere, but about half the reported cases present on the dorsa of hands and feet, whereas the plaque-type blue nevi occur mainly on the trunk and extremities. Histopathologically, the plaque-type blue nevi are reported to be common or cellular. We report a rare case of plaque-type blue nevus on the right temporal area in a 32-year-old female.
