A Case of Disseminated Superficial Actinic Porokeratosis Successfully Treated With Topical Lovastatin/Cholesterol Gel

Disseminated superficial actinic porokeratosis (DSAP) is a disorder of abnormal keratinization for which there is no standard treatment. Treatment modalities that have traditionally been utilized with varying success include ablative therapies, topical pharmacologic treatments, surgical excision, and retinoids. The underlying pathophysiology of DSAP is secondary to genetic mutations in the mevalonate biosynthesis pathway, and thus topical lovastatin/cholesterol presents a promising treatment modality for this condition. We present a case of familial DSAP successfully treated with topical lovastatin/cholesterol gel and provide a brief review of the existing literature surrounding this novel therapy.
