Eosinophilic pustular folliculitis (EPF) in a patient with HIV infection.

Eosinophilic pustular folliculitis is a chronic, recurrent dermatosis, of unknown etiology, which is histologically characterized by folliculotropic inflammatory infiltrates with admixed eosinophils in the dermis. It has often presented with immunosuppression and especially with HIV-Infection. In the HAART-era, eosinophilic pustular folliculitis has become a rarity. It is often being misdiagnosed as acne vulgaris, rosacea, bacterial folliculitis, dermatomycosis and seborrheic dermatitis. The treatment of this disease may be difficult.
