Intrapulmonary lymph node diagnosed by thoracoscope: a case report

A 62-year-old man was admitted to our hospital because of abnormal shadow on chest X-ray. Chest X-ray and CT showed a subpleural tumor 12 mm in diameter in the S8 segment of the right lung. Thoracoscopic observation revealed a subpleural black nodule. Wedge resection of the S8 segment was performed. Pathologically, the nodule was diagnosed as an intrapulmonary lymph node. It should be noted that thoracoscope was very useful for differentiation of intrapulmonary lymph node from other small malignancy.
