  "abstract": "A 53-year-old male manual labourer presented for evaluation of a solitary nodule in the left lower lobe. The lesion had initially been detected incidentally during a health check-up 7 years earlier and had enlarged over the preceding 2 months. The patient reported an intermittent productive cough with mucoid, blood-streaked sputum. He did not smoke and had received empirical four-drug antituberculosis therapy 1 year earlier for an unconfirmed left lower lobe pulmonary opacity, without substantial symptomatic or radiological improvement. Chest CT revealed an enlarging subpleural nodule with increasing solid components in the left lower lobe, without mediastinal lymphadenopathy, raising concern for an early-stage primary lung malignancy (figure 1A). Given the diagnostic uncertainty, video-assisted thoracoscopic surgery (VATS) wedge resection was performed.",
