The adult type pulmonary hamartoma in an 11-year-old boy.

Hamartoma of the lung occurs most often in persons after the age of 40, but quite rarely among children. This paper reports on an 11-year-old boy with a pulmonary hamartoma in the right upper lobe. The patient was asymptomatic, but a well demarcated, solitary, lobulated nodule with a "popcorn"-shaped calcification was visualised on chest x-ray film. An upper lobectomy was carried out to remove the lesion. The post-operative course was uneventful. Two years post-operatively, the child was symptom-free and has been developing normally.
