Background. Pneumothorax with lung cancer is a rare entity, with an incidence of 0.05-1.13% of cases. Case. A 44-year-old male who developed right-sided hemopneumothorax with severe dyspnea and back pain was referred to our hospital. Due to prolonged air leakage, he underwent video-assisted thoracoscopic surgery for pneumothorax. A histological examination of the resected lung showed squamous cell carcinoma lining the inside of the bullae with pleural perforation. Under the diagnosis of primary lung cancer, the patient underwent right upper lobectomy with lymph node dissection (pT2aN0M0). He has been free from recurrence for 6 months after the operation. Conclusion. Patients with hemopneumothorax who are associated with various risk factors, such as an advanced age, heavy smoking, or emphysematous lung cysts, therefore require a careful assessment for occult lung cancer.
