Abstract

Demodex folliculorum is a saprophytic mite of the human pilosebaceous unit with a prelidiction for facial skin and eyelashes. Infestation occurs frequently without symptoms; however, suppurative or granulomatous inflammation may be seen with high mite density. Skin lesions, such as rosacea, pityriasis, and blepharitis, have been attributed to Demodex; however, its role in sebaceous adenoma (SA) has not been reported in extensively searched medical literature. We report this rare case and review the skin lesions associated with Demodex folliculorum.
