Abstract
A 54-year-old man with a history of smoking developed infectious bullae at the apex of his left lung and underwent long-term antimicrobial treatment. The bullae gradually reduced in size along with a slight left pleural thickening. Left back pain relapsed after a year, and CT revealed a rapid increase in pleural thickening. Left upper lobectomy led to the diagnosis of pulmonary polymorphic carcinoma. Chronic inflammation due to infection could contribute to carcinogenesis; therefore, post-inflammatory changes should be carefully followed-up.
