MOLINARI, Luciana et al. Wegener's granulomatosis and tuberculosis: A bad combination. Medicina (B. Aires) [online]. 2009, vol.69, n.6, pp.640-642. ISSN 0025-7680.

Wegener's disease is a vasculitis of small and medium-sized vessels associated with anti-neutrophil cytoplasm antibodies (ANCA). Within their target organs the lungs are involved in 85% of cases. Many entities are part of the differential diagnosis, including pulmonary tuberculosis. We present the case of a 54 years old man, diagnosed as Wegener's disease in 1996 which begins in August 2007 with cough, hemoptysis, progressive dyspnea on effort and serial sputum positive for AFB and then starts TB treatment. Subsequent bronchoalveolar fluids resulted negative for AFB. The patient evolved with impaired renal function, palpable purpura and positive anti-neutrophil cytoplasm antibodies cytoplasmic pattern (c-ANCA), interpreted as Wegener's disease relapse. He started hemodialysis and immunosuppressive therapy and tuberculosis treatment was stopped. One month after discharge was readmitted with a similar picture with serial sputum positive for AFB.
