title: Pseudomelanoma: recurrent melanocytic nevus following partial surgical removal.
abstract: Histological markers enable the correct diagnosis of a pigmented lesion that histologically resembles a superficial spreading malignant melanoma and yet behaves in a wholly benign way. This pseudomelanoma occurs in young adults within a few weeks following partial surgical-shave excision of an intradermal melanocytic nevus.
