Linear porokeratosis: A case report and review of the literature

Abstract

Linear porokeratosis refers to 1 of 5 variants of porokeratosis. Porokeratosis is a keratinization disorder of multiple etiologies including genetic aberrancy, trauma, and infection. We review a case of a 35-year-old man with a chronic history of linear porokeratosis and conduct a review of porokeratosis subtypes, etiology, histology, pathology, differential diagnosis, and treatment.
