Background. While the coexistence of sarcoidosis and lung cancer is unusual, when such case is encountered, there is a possibility that appropriate treatment for lung cancer is not selected because of overestimation of mediastinal lymphadenopathy. Case. A 60-year-old woman was admitted for evaluation of abnormal shadow on chest imaging studies. Chest computed tomography revealed a mass (23 mm) in the right lung (S2) and pretracheal (#3) lymphadenopathy of minor axis 11 mm. The mass was diagnosed as adenocarcinoma of the lung by transbronchial washing and brushing cytology. The preoperative diagnosis was clinical stage IIIA (T1N2M0) adenocarcinoma of the lung. Right upper lobectomy and mediastinal lymph node dissection (ND2a) was performed. Pathological findings revealed non-caseating granulomas in both most of the lymph nodes and the resected lung without any lymph node metastasis. Conclusion. We reported a p-stage IA (T1N0M0) adenocarcinoma of the lung with sarcoidosis. We must endeavour never to overlook a resectable case of lung cancer.
