Pustular folliculitis associated with Demodex folliculorum.
A 49-year-old man presented with an acute onset of folliculitis on his right cheek. The folliculitis was unresponsive to antibiotics. A potassium hydroxide preparation of a scraping from the affected area revealed the presence of numerous Demodex mites. The patient was treated with topical crotamiton (Eurax) cream resulting in rapid resolution of the folliculitis. We believe that this case represents a localized pustular folliculitis resulting from a heavy infestation with Demodex folliculorum. In spite of more than 50 years of investigation, the role of D. folliculorum in human cutaneous disease remains controversial.
