ABSTRACT
Abstract Small vessel vasculitis with anti-proteinase antibodies 3 is an atypical clinical presentation of tuberculosis. The authors present the case of a 47-year-old male patient, with palpable purpura and palmoplantar hemorrhagic blisters, with subsequent dissemination. He presented severe pulmonary symptoms with cavitation, fever, hemoptysis, and high levels of anti-proteinase 3. Histopathological assessment of the skin revealed small vessel vasculitis; pulmonary histopathology showed granulomas with caseation. Bronchoalveolar lavage was positive for alcohol-acid-fast bacilli. In countries with a high prevalence of tuberculosis, the presence of autoantibodies in a patient with vasculitis, fever, and pulmonary cavitation requires investigation of infectious causes.
