title: Facial porokeratosis: A series of six patients.
abstract: Porokeratosis is a disorder of epidermal keratinization characterized by annular plaques with an atrophic centre and hyperkeratotic edges, and includes a heterogeneous group of disorders that are mostly inherited in an autosomal dominant fashion. Facial porokeratosis is rare and is not well documented. We present six cases of facial porokeratosis seen over a period of 15 years in a hospital in Lima, Peru. In most of the cases, porokeratosis was found in younger women without any significant past medical history. Oral isotretinoin showed moderate improvement in two of our patients.
