Disseminate and recurrent infundibulofolliculitis

Abstract： Disseminate and recurrent infundibulofolliculitis (DRIF) is an uncommon pruritic follicular eruption of unknown etiology that is predominantly seen in black men. This condition tends to affect the trunk and upper extremities and is usually unresponsive to local and systemic treatment. Herein, we report a 28-year-old women presented with an asymptomatic brown eruption of 4 years duration. She had brown-colored follicular papules involving predominantly over the neck, chest and abdomen. Histopathology revealed spongiosis of the follicular infundibulum and infiltration with lymphocytes and neutrophils. Treatment with oral vitamin A and topical retinoic acid was ineffective.
