Becker's Nevus with Underlying Neurofibroma / 대한피부과학회지

ABSTRACT

Becker's nevus is a common and acquired focal epidermal melanotic hypermelanosis characterized by a large, unilateral patch showing hyperpigmentation and hypertrichosis on the shoulder, back or chest of a man around puberty. In some cases, it is associated with hamartomatous proliferation of pilosebaceous or dermal component including smooth muscle, connective tissue and nerve sheath. According to these findings, some authors suggested that Becker's nevus could be an organoid hamartoma accompanied by variable proliferation of epidermal and dermal components. We herein report a case of Becker's nevus associated with underlying neurofibroma in a 30-year-old man, which might be another evidence supporting that suggestion.
