We report the case of a patient with leukocytoclasic vasculitis that disclosed active pulmonary tuberculosis. This patient had no signs of systemic vasculitis. The clinical course was favorable with anti-tuberculosis drugs alone. There has been no recurrence at 8 months. Vasculitis associated with tuberculosis is uncommon. The pathophysiological mechanism remains uncertain. No immunosuppressor treatment is needed and the vasculitis generally regresses with treatment of the infection.
