Disseminated and Recurrent Infundibular Folliculitis (D.R.I.F.): Report of a Case Successfully Treated with Isotretinoin

Disseminated and recurrent infundibular folliculitis, henceforth referred to as D.R.I.F., is a very rare, puritic, follicular, benign disease of unknown etiology seen mostly in black males. It is often self‐limited and usually unresponsive to local or systemic treatment. However, vitamin A, either alone or combined with vitamin E, is occasionally effective. We report a case of a patient with D.R.I.F. treated successfully with isotretinoin.
