Background: Primary lung cancer with thin-walled cavity is rare. There are few reported cases of lung cancer with a thin-walled cavity presenting a round shadow on a chest X ray. Case: A 59-year-old man was admitted for further examination of a round shadow on a chest X-ray. The shadow had been an irregular lesion with a thin-walled cavity six months previously. The patient rejected bronchoscopic examination and thoracoscopic resection was performed. Histological examination revealed the tumor to be squamous cell carcinoma. Right lower lobectomy and mediastinal lymphadenectomy was performed subsequently. The tumor was 50 mm in diameter. It was filled with a white jelly-like substance. Microscopic examination showed well differentiated squamous cell carcinoma in a wall of the cavity and the substance. The pathological stage was IB (T2N0M0). He is well and disease-free ten months after the operation. This is thought to be a very rare case of primary lung cancer with thin-walled cavity which presented an atypical round shadow on chest X-ray. Conclusion: Aggressive treatment including VATS is considered to be necessary for abnormal shadows on chest X-ray presenting a thin-walled cavity in which lung cancer is suspected.
