title: [Case of adenocarcinoma in situ accompanied by an intrapulmonary lymph node with a sarcoid-like reaction].
abstract: A 65-year-old male underwent a chest CT scan, which revealed an 8 mm nodule on the wall of a bulla in the left lower lobe of the lung, and was thus suspected to be lung cancer. Pulmonary wedge resection of the left lower lobe by means of video-assisted thoracoscopic surgery was thus performed. A specimen of the lung revealed the presence of intrapulmonary lymph node on the wall of a bulla. The histopathological findings of the resected lung specimen showed non-caseating granulomas in the lymph node, and adenocarcinoma in situ. We concluded that the sarcoid-like reaction observed in the intrapulmonary lymph node was therefore related to the adenocarcinoma in situ.
