[A case of giant hamartochondroma of the lung].

The authors present a case of pulmonary hamartochondroma of exceptional size, of which they give a clinical descrition and explain the surgical treatment. Next, aloso in the light of recent literature on the subject, they review the possible causes of this disorder in terms of several histopathogenetic hypotheses, and they discuss problems of differential diagnosis as well as the histopathological aspects of this rare, benign tumor of the lung. They conclude that even though malignant transformation of hamartochondroma is exceptional, these tumors should always be removed surgically as soon as they are diagnosed or reasonably suspected.
