Digitate keratosis-a complication of etretinate used in the treatment of disseminated superficial actinic porokeratosis

Abstract

We report a patient with disseminated superficial actinic porokeratosis (DSAP) who developed digitate keratoses following treatment with etretinate. The aetiology of these digitate keratoses is discussed and their similarity to post irradiation conical keratoses (PICK) is highlighted.
