Abstract. A retrospective analysis of 150 outpatients of patients who have received prior treatment for malignant tumors of various localizations. In those patients the round shadows were revealed in the lung at different times after treatment. Patients were divided into two groups: 85 patients with multiple primary lung cancer and 65 patients with metastatic lung lesion. Thus, received data indicate that the first stage and localization of tumor are important characteristics that can be used for differential diagnosis of primary multiple and metastatic lung tumors. Considering that the exact diagnosis can be established only after the histological conclusion we consider that surgical step should be mandatory when primary multiple and metastatic lung tumors are suspected.
Key words: multiple primary cancer, metastatic lung involvement, differential diagnosis.
