Cutaneous leukocytoclastic vasculitis revealing multifocal tuberculosis.

Cutaneous leukocytoclastic vasculitis (CLV) is an inflammatory vascular disorder rarely reported to be associated with tuberculosis. The following report describes the case of a young man with multifocal tuberculosis revealed by CLV. Diagnosis was confirmed by the presence of tuberculoid granuloma with caseous necrosis on pleural and perianal biopsy, and a rapid improvement in anti-tuberculous quadritherapy. Although rarely seen, Mycobacterium tuberculosis should be considered as a potential cause of CLV.
