[Eosinophilic pustular folliculitis in acquired immunodeficiency syndrome. Report of 6 cases]. / Foliculitis pustulosa eosinofílica en el síndrome de inmunodeficiencia adquirida. Presentación de seis casos.

Eosinophilic pustulous foliculitis (EPF) is a rare dermatosis which has been reported in association with the human immunodeficiency virus infection. Six patients infected with HIV are reported with advanced disease in whom the diagnosis of EPF was made. All patients has a highly pruritic follicular papular rash. In all cases the pathology study revealed a mixed inflammatory infiltrate with predominance of eosinophils at the infundibulum of the pilous folliculi. Two patients had eosinophilia in peripheral blood. Therapy with antihistaminic agents and topical corticosteroids was ineffective in all cases. A favourable therapeutic response was achieved with phototherapy associated with the topic application of disodium cromoglycate 4%.
