[Clear cell acanthoma].

We present a case of clear cell acanthoma localized on inferior third of the external portion of the left leg, the evolution was of one and a half year, with previous insect bites on the area. We insist on the histologic appearance, characterized by hyperplasia of epithelial cells, intercellular bridges, and presence of acidophilic hyalins intracytoplasmiques. Nous postulons la possibility of a viral etiology, transmitted by insect bite, of an epidermotropal virus.
