title: Pulmonary carcinoma associated with hamartoma in an 11-year-old boy.
abstract: OBJECTIVE
  We describe a poorly differentiated adenocarcinoma of the lung in an 11-year-old boy who had had a pulmonary hamartoma for at least 8 years.
  
  
  CONCLUSIONS
  A hamartoma, even if clinically silent, may lead to the development of malignant tumors on rare occasions.
