A Case of Annular Leukocytoclastic Vasculitis / 대한피부과학회지

ABSTRACT

Leukocytoclastic vasculitis is characterized by necrotizing, neutrophilic inflammation of small dermal blood vessels usually presenting as palpable purpuric lesions. Different clinical forms such as urticarial wheals, nodules, bullaes, ulcers and pustules have been less commonly encountered. Annular lesions have been rarely reported in the clinical spectrum of leukocytoclastic vasculitis. Herein we present a case of purpuric eruptions with unusual centrifugal evolution, creating polycyclic patches on both lower extremities. Histopathologic examination revealed compatible features of leukocytoclastic vasculitis.
