[Sarcoidal reaction in lung adenocarcinoma in 50-years old man].

A 50-year old patient was admitted to the hospital with hoarseness persisting for two weeks. Chest computed tomography revealed enlargement of lymph nodes in the aortopulmonary window. The bronchoscopy did not show any abnormalities, in transbronchial fine needle aspiration biopsy no diagnostic material was obtained. In the biopsies collected during mediastinoscopy the sarcoid granulomas were recognized. In the follow-up the computed tomography revealed a tumor mass and diagnostic thoracotomy was performed in which pulmonary adenocarcinoma was recognized. After radiotherapy the total regression was achieved. In this case sarcoid-like reaction in the course of lung cancer and the diagnostic difficulties were described.
