Koebner phenomenon in leukocytoclastic vasculitis: A case report and an updated review of the literature

Abstract

Leukocytoclastic vasculitis is the most common form of cutaneous vasculitis. It is a neutrophilic small vessel vasculitis resulting from the deposition of circulating immune complexes. Henoch-Schonlein purpura is a systemic type of leukocytoclastic vasculitis, characterized by immunoglobulin A-mediated blood vessel injury. We present a case of Henoch-Schonlein purpura in an adult female manifesting with a vasculitic rash with Koebner phenomenon.
