A Case of Leukocytoclastic Vasculitis Associated with Pulmonary Tuberculosis / 대한피부과학회지

ABSTRACT

Leukocytoclastic vasculitis is characterized by palpable purpura, showing microscopically necrotizing vasculitis of the small dermal blood vessels. Although various causes have been suggested, cases of leukocytoclastic vasculitis associated with tuberculosis have rarely been reported. A 40-year old man presented with palpable purpura on both ankles, an intermittent cough, low-grade fever and recent weight loss. A skin biopsy showed characteristic features of leukocytoclastic vasculitis, and the findings of radiology and sputum examinations were compatible with active pulmonary tuberculosis. The purpuric lesions gradually subsided after antituberculous medication. The findings suggested cutaneous leukocytoclastic vasculitis accompanied by pulmonary tuberculosis.
