Introduction: Pulmonary tuberculosis is associated with symptoms, signs and radiological images similar to those of lung cancer; therefore, it can simulate a neoplasia. In the case of resistant bacteria and the lack of first-line drugs, combined treatments are used, which in many cases have no evidence of their effectiveness.
Objective: To contrast the results of diagnostic investigations with the clinical manifestations in a patient with pulmonary and colon tuberculosis.
Clinical Case: Patient with pulmonary tuberculosis, with risk factors, clinical and radiological manifestations of lung cancer; he was evaluated with this diagnosis until months later the bacilloscopy and biopsy confirmed the diagnosis. Exceptional treatment with first- and second-line drugs was indicated in the first phase. The patient evolved favorably.
Conclusions: Pulmonary tuberculosis can go unnoticed, because it is asymptomatic or simulates a pulmonary neoplasia. Bacilloscopic examination is an essential tool for differential diagnosis and timely treatment, which in this case produced clinical-radiological and bacteriological improvement.
