title: Keratoacanthoma Arising in an Organoid Nevus (nevus Sebaceous).
abstract: Organoid nevi may rarely be complicated by development of keratoacanthoma. We report a 21-year old man who presented with a hyperkeratotic papule developing over a well demarcated hyperpigmented irregular plaque on the forehead. Histopathology revealed features suggestive of keratoacanthoma developing in a lesion of nevus sebaceous. Literature search revealed 11 such reported cases. Most of the reported patients were young and had lesions on the face. Such lesions should be excised completely to prevent any malignant change in the future.
