ABSTRACT
Two patients, a young woman and a young man, with mucoepidermoid carcinoma of the lung, who were diagnosed at the Department of Phthisiopneumonology in Zabrze Silesian Medical University in Katowice are described. The principal method of diagnostics in the presented cases were bronchofiberoscopy followed by the histopathological examination of the lesions. There are no cases of massive bleeding as the side effect of this procedures described. This type of carcinoma of the lung is mostly found in young patients, usually without any risk factors of lung cancer, what confirms the rule, that all pulmonological symptoms of unknown origin should be verified by bronchoscopy, because other methods of diagnostics, including TC of chest-like in our patient, may be false-negative. The method of choice in the treatment of mucoepidermoid carcinoma is surgery. One should avoid a through bronchoscope resection, as it may be only partial. Metastases, mostly found in the local lymph nodes, are rarely described.
