[Epitheloid cell granulomas in bronchial invasive mucinous adenocarcinoma].

Granulomatous lung diseases are frequently occurring pulmonary diseases.Important granulomatous lung diseases are sarcoidosis and pulmonary tuberculosis. Furthermore, granulomas can be caused by foreign body reactions like berylliosis or silicosis as well as by other infections (e. g. by nocardia spp.).Granulomatous systemic inflammatory diseases such as the Churg Strauss syndrome or the Wegener's granulomatosis can harm the lung as well.In this case report, we describe a patient who visited our emergency room because of apparent refractory pneumonia. First histologic specimens showed sarcoid-like lesions. Subsequent investigation showed invasive mucinous adenocarcinoma of the lung.
