Abstract:
Deep penetrating nevus is a distinctive entity first described by Seab et al. in 1989. This is a variant of melanocytic nevus found on the face, the upper part of the trunk, and the proximal part of the limbs of young adults. It is often deeply pigmented with some variegation in color, and it may lead one to a misdiagnosis of blue nevus or malignant melanoma. Histopathologically the lesions are composed of loosely organized nests of slightly to distinctively pleomorphic pigmented cells that deeply penetrated reticular dermis and often extended into the subcutis. There have been no report of deep penetrating nevus in the Korean literature. We report a case of deep penetrating nevus occurring on the chest in a 19-year-old male.
