Hamartoma had been considered as a congenital malformation of a tumerous lesion since the original description by Albrecht in 1904. Pulmonary hamartoma is able to classified as endobronchial and intrapulmonary hamartoma clinically, and is considered to benign mesenchymal neoplasms which originated in peribronchial connective tissue, and so called mesenchymoma by someone. We have experienced 3 cases intrapulmonary hamartoma which were discovered during routine chest film check up at all cases and are able to detailed histologic examination by electron microscopy at one case.

The hamartoma is the commonest benign tumor of the lung and proved incidentally as asymptomatic coin lesion on routine chest radiologic examination, but has very low incidence, especially in endobronchial origin. The authors experienced a case of coincidental with intrapulmonary and endobronchial hamartoma. The patient, a 60-year-old man, a farmer, was admitted due to coughing and fever. Preoperative diagnosis was achieved by flexible bronchoscopic biopsy and managed by right middle lobectomy. Three lobulated masses were palpable in the right middle lobe. He was discharged on 15th postoperative day, without problem.

Background: Pulmonary hamartomas are benign tumors that occur in the parenchyma or in the bronchi. They present as a solitary pulmonary nodule(SPN) or as a cause of bronchial obstruction. The incidence, once minimal, is increasing in Korea. To get clinical spectrum about the tumor, we analyzed all the reported cases in Korea since 1964. Methods: We reviewed the clinical, radiological and pathological findings of 13 patients of intrapulmonary or endobronchial hamartomas in Severance Hospital and of 38 reported cases in Korea published in literatures from 1964 to 1992 retrospectively. Results: Including 17 endobronchial hamartomas, 54 cases were studied. There were 25 men and 29 women, with a mean age of 47.2 years; 45.3 years in endobronchial type and 51.3 years in parenchymal type. Pulmonary symptoms were present in 8 patients (22%) of intrapulmonary type and in all patients of endobronchial type: cough (65%), dyspnea (53%), sputum (35%), fever (29%) in order. On chest X-rays, atelectasis was seen in 10 patients (59%) in endobronchial type; but SPN was noted in 36 patients (97%) of intrapulmonary type. Calcification was present in 7 intapulmonary hamartomas (23%); but is in 2 endobronchial hamartomas (12%). The diagnostic yield was 6 out of 14(43%) in endobronchial ones; 4 out of 7(57%) in intrapulmonary ones. Fifty patients underwent operations as follows: lobectomy (28), enucleation (8), resection (8), bilobectomy (4), pneumonectomy (2). The hamartomas were 1.2 times more common in the right lung; mean transverse diameter at the time of operation was 2.3 cm in endobronchial type, 3.8 cm in intrapulmonary ones. Chondroid components were present in 11(65%) of 17 endobronehial ones but in 30(91%) of 33 intrapulmonary hamartomas. No malignant changes were seen perioperative period and up to early 1993. Conclusion: The younger age in endobronchial hamartomas, the preponderance of the female sex and the more incidence in the right lung, and the diagnostic choice of lobectomies were different from the studies of the Western countries.
