Demodicidosis on the arms of a patient with pemphigus foliaceus

Abstract

Demodex mites are common commensals of the human pilosebaceous follicle that use sebum as nourishment. They are most frequently found on the face, where the number of sebaceous glands is greatest, but they have also been observed on the ear canal, scalp, neck, back, chest, nipples, buttocks, and penis. To our knowledge, there is only 1 case report of demodectic mites on the extremities (legs). Here we report a case of demodicidosis on the arms.
