title: Sebaceous adenitis.
abstract: A 32-year-old man had an asymptomatic erythematous, annular and circinate eruption on the face for 2 months. Histologic examination revealed sebaceous lobules surrounded by a lymphomonocytic infiltrate and some areas of necrotic sebocytes. The lesions healed without treatment in 1 month. These clinical features can be observed in "neutrophilic sebaceous adenitis," recently described by Renfro et al. The most striking abnormality is the nearly exclusive perisebaceous distribution of the dermal cellular infiltrate with inflammatory cell permeation of the sebaceous epithelium.
