説明

Forty-six cases of surgically resected pulmonary hamartoma in our hospital during a 10-year period (1989_??_1998) were subjected to a study of clinical characteristics. They were 23 male and 23 female patients and ranged in age from 26 to 77 years (mean 57.7±12.1). We studied a total of 48 lesions including two multiple cases. The size of the tumors varied in diameter between 5 and 32mm (mean 12.1±6.0). Thirty-four pulmonary lesions were on the right lung (upper: 15, middle: 6, lower: 13) and 14 lesions were on the left lung (upper: 8, lower: 6). Thoracotomies were carried out for them. Operative procedures included enucleation for three, wedge resection for 38, segmentectomy for two and lobectomy for five cases. In all cases, no preoperative diagnosis was made and pulmonary hamartoma was diagnosed by intraoperative frozen section diagnosis. No local recurrence has been detected in these cases. We conclude that less invasive surgery such as thoracoscopic surgery or enucleation should be selected for the surgical treatment of pulmonary hamartoma.
