The paper describes a giant chondroid pulmonary hamartoma (CPH) with multiple nodular structure, diagnosed in young men by chest X-Ray. According to CT giant tumor was located in the lower lobe  of the left lung and was formed by merging nodes and crypts with “popcorn” calcifications with irregular thickened bronchial walls. The patient underwent left lower lobectomy. Results of pathological examination of  pulmonary tumor showed  merging nodes with plate-branched structure and focal calcificated lobules of mature hyaline cartilage, separated by layers of fibrous connective and fatty tissue. The distinctive radiographic and pathologic features of this case are the giant size of CPH and its multiple nodular structure. The giant CPHs are extremely rare, especially with multiple nodular structure, are not mentioned in main radiological and pathological guidelines and classifications, and have some radiographic and pathological features. Radiological and  morphological features of this case confirmed  high value of pulmonary CT as the optimal visualization method of calcifications and fat inclusions in  tumor tissue. Fat tissue in a slowly growing tumor node is a reliable criterion of CPH, that can facilitate pre-operative verification and thereby improve the quality of care.

Key words: giant pulmonary chondroid hamartoma, radiographic and morphologic signs.
