Lung Carcinoma Superimposed on Pulmonary Tuberculosis

Abstract

Review of patients with active pulmonary tuberculosis over a three-year period showed an increased incidence of bronchogenic carcinoma (5%). There had been considerable delay in establishing diagnosis of coexistent carcinoma which was attributed to finding of acid-fast bacilli and relative ease of ascribing all findings to that cause. Suspicious roentgen signs are reviewed and the importance of sputum cytology is also stressed.
