Acne is one of the common skin disorders, with multifactorial chronic inflammatory disease of
pilosebaceous units. Demodex folliculorum is an obligate parasite of pilosebaceous units, infested
healthy individuals. The study detected D. folliculorum mites in acne patients and discussed
its role in acne. The study was conducted on 500 acne patients attending outpatient clinic of
Dermatology Department, University Hospitals. Superficial skin surface sampling or sometimes
skin scrapings were taken from patients (290 females & 210 males). They were children 244
(48.4%), adolescent 206 (41%) and elder 50(10%), with ages ranged from 13 to 35years (18.36
±3.9), rural residents (323), and (177) urban ones. Mites in acne patients were detected in 8/500
(1.6%), significantly more detected among adolescents and cases with severe clinical disease (P
= 0.027 & 0.001 respectively). D. folliculorum in acne patients didn't show significance difference
as to sex, residence or treatment history (P > 0.05).
