Setting:
South Granada Health Area (SGHA), Spain.
Objective:
To describe the characteristics of concomitant tuberculosis (TB) and lung cancer cases.
Design:
A total of 319 TB cases diagnosed between January 2003 and December 2010 were evaluated and identified using a prospective database. During this period, samples of bronchial secretions were obtained from all patients who underwent fibreoptic bronchoscopy (FBS) as part of a TB screening programme. A descriptive study was conducted.
Results:
Concomitant TB and lung cancer were diagnosed in 15 cases (4.7% of total TB cases). The most common radiographic finding was atelectasis (53.3%), and the most common histological type was epidermoid carcinoma (60%). Lung cancer stage was advanced (III-IV) in 60% of the cases.
Conclusion:
The association between TB and lung cancer found in the SGHA after implementing a TB screening programme was higher than in other studies. This suggests that it would be advisable to perform acid-fast bacilli smear and mycobacterial culture of bronchial aspirates in all patients with presumed lung cancer, particularly in high TB prevalence areas.

Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
