Introduction:
Lung cancer is the leading cause of cancer-related mortality worldwide. Although lung cancer is predominantly observed in smokers, non-smoking patients account for 20% of cases worldwide. In this article, we present a case of lung adenocarcinoma that originated from a postoperative scar. We present a 62-year-old male patient who, while being studied for Paget's disease of bone, presented a 1.5 cm pulmonary nodule (SUV 1.6) as an imaging finding in the posterior segment of the left lung. He underwent a upper left lung segmentectomy.
Results:
During the routine follow-up of his underlying disease, 12 years after the original surgery, a pulmonary nodule was found. The particularity of the sample is based on the macroscopic observation of the tumor piece where the development of the neoplastic mass on the mechanical suture of the previous surgery performed 12 years ago is shown.
Conclusion:
We describe a rare cancer development mechanism in clinical practice, from chronic postoperative inflammation due to mechanical suturing.
