We report 3 cases of pruriginous papular eruption of HIV disease, in w
hich demodectic mites were found in the pilosebaceous follicles which
were surrounded by a granulomatous inflammatory infiltrate. Papular er
uption of HIV disease is a distinctive clinicopathological entity, who
se pathogenicity is not known. Our observations suggest that demodecti
c mites might be sometimes the etiologic agents of this eruption.
