Results: It was reported the case of a patient that was diagnosed with leukocytoclasticvasculitis (LV) for six months and was admitted presenting granulomatous lung injury, weight loss, fever and dry cough for eigth months. The delay in the diagnosis of tuberculosis (TB) allowed an evolution to TM and the late onset of treatment impaired the patient’s prognosis. It was discussed the vasculitis as a first symptom of tuberculosis, which can occur by deposition of immune complexesformed by antibodies against antigens of bacilli in the vascular wall. Conclusions: Previous diagnosis of LV deviated the focus of the case for their cause, and suggested other pathologic conditions, which contributed to delay in the diagnosis of TB. Despite the late diagnosis and treatment, the therapeutic approaches used for vasculitis, TB and TM followed the protocols described in the literature.
