Coexistence of lung squamous cell carcinoma and pulmonary tuberculosis within a single lesion: a case report

Abstract Background: Tuberculosis and lung cancer are common high-mortality lung diseases, but it is rare that lung cancer and tuberculosis exist in the same lesion. In addition, lung cancer with pulmonary tuberculosis is similar in morphology to lung cancer without tuberculosis. For these reasons, lung cancer patients with tuberculosis are often misdiagnosed and mistreated, so these patients have a poorer prognosis than lung cancer patients without tuberculosis. Therefore, a full understanding of such cases can help early diagnosis, so that appropriate treatments can be performed timely. Case presentations: A 52-year-old male. The physical examination revealed a cavity-like nodule in the upper left lung and the first diagnosis was tuberculosis. There was no significant change in lung nodules after anti-tuberculosis treatment. So the patient was admitted to the hospital for surgical treatment of lung cancer. Postoperative pathological showed that the lesion was lung squamous cell carcinoma with tuberculosis.Conclusion: the survival rate of patients with active pulmonary tuberculosis and lung cancer is lower than those with lung cancer or tuberculosis alone. Which is mainly due to incomplete diagnosis. if we find hollow shadows in the lungs on CT, we should think about the possibility of coexistence of lung cancer and tuberculosis, and then the appropriate treatment and management strategies should be developed..
