title: [Folliculitis granulomatosa perforans profunda: an independent perforating dermatosis?].
abstract: A peculiar perforating dermatosis was observed in two adolescent male patients consisting of a persistent, disseminated, asymptomatic, follicular, discretely hyperkeratotic papular eruption. Histologically a massive granulomatous panfolliculitis was present with partial destruction of the pilary complex and occasional perforation of hairs through the infundibular wall. Aggregations of keratin fragments were scattered throughout the corium. These histological findings clearly separate the condition from perforating folliculitis, pityriasis rubra pilaris and Kyrle's disease. Differentiation from the perforating type of keratosis pilaris is more difficult.
