Seven years after his diagnosis the patient presented a new relapse with cavitary lung disease, and high levels of anti-proteinase 3 antibodies, suggesting disease activity; however, a transbronchial biopsy showed histological findings of tuberculosis (TB). The association between TB and GPA is rarely informed; moreover TB and GPA have similar findings including both clinical and anti-proteinase 3 antibodies. ER -
