[Association between early peripheral lung cancer and nontuberculous mycobacterial lung disease]

Mycobacteriosis is an infectious disease caused by nontuberculous mycobacteria, with granulomatous inflammation in the affected organs and tissues. The association of mycobacteriosis and lung cancer in one patient is quite rarely observed and is of interest to the medical community. A 63-year-old male patient was admitted to the hospital with a diagnosis of infiltrative tuberculosis in SI-SII of both lungs in the lung cavitation phase on the right, peripheral mass in SIII on the right in order to make a decision about a surgical intervention. Morphological examination of the material obtained during upper lobectomy revealed mucinous adenocarcinoma concurrent with mycobacterium-associated inflammation with cavern formation. A bacteriological study confirmed the presence of the pathogen Mycobacterium avium. This study reports a case of association of the diseases with successful surgical intervention without complications in the early postoperative period.
