[Cartilaginous hamartoma of the thoracic wall in a newborn infant].

Thorax neoplasms are very rare in newborn. We present a case of cartilaginous hamartoma arising from the ribs. Clinical appearance of this kind of tumour might be even typical as its roentgenogram and surgical intervention can be done immediately. If the histopathological diagnosis is in accordance with the other findings no other therapy is required. To our knowledge no case is reported in which malignancy has been seen or discovered at a later date.
