Cutaneous small vessel vasculitis and pulmonary tuberculosis: an unusual association

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.

Tuberculosis should not be ignored in patients with peripheral gangrene

Peripheral gangrene, characterized by distal ischemia of the extremities, is a rare complication in patients with tuberculosis (TB). We diagnosed a female patient with gangrene of her left toe caused by TB infection. She presented with fever, lymphadenectasis, and peripheral gangrene of the left toe. Lymph node biopsy confirmed tuberculous lymphadenitis and the computer tomography angiography showed vasculitis. The patient underwent antituberculous therapy and her condition was gradually improved. Although it is rare, TB should be considered as a possible cause of peripheral gangrene.
