Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - Eosinophilic folliculitis, commonly seen in advanced HIV patients, is a pruritic skin eruption usually involving the face, neck, trunk, and extremities manifesting in the form of pustules and papules. The skin lesions usually start as small pustular groups that later coalesce to create irregular erosions and plaques with central hyperpigmentation. The associated pruritus is often so intense that the lesions become excoriated. Most patients with this condition will demonstrate CD4 cell counts of less than 250/mm3. The etiology of eosinophilic folliculitis is unknown but is commonly thought of as an inflammatory process associated with immune dysfunction. It has become less common with the advent of HAART.
