Henoch–schonlein purpura (HSP) is an acute, systemic, immune complex mediated, leukocytoclastic vasculitis seen more commonly in children. It presents with the clinical triad of non–thrombocytopenic palpable purpura, arthritis and abdominal pain. We present a case of disseminated tuberculosis associated with HSP in a 57 year old male patient, who developed non–pruritic, painless purpura after six days of anti–tuberculosis treatment. The skin biopsy revealed granular blood vessel wall staining with IgA, C3 and fibrinogen suggestive of HSP. The cutaneous vasculitis in this disappeared with the continuation of anti–tubercular drugs. The association of tuberculosis and HSP is very rare.
