Abstract
Background: Pulmonary hamartomas are the most common form of pulmonary benign tumors, and they occur in approximately $2{\sim}5%$ of all pulmonary neoplasm. However, only a few reports have been published on the clinical characteristics of pulmonary hamartoma in Korea. Material and Method: The charts, X-rays and pathological specimens of 37 pulmonary hamartoma patients who were diagnosed by a pathological examination from January of 2000 to May of 2005 at the Catholic Medical Center were retrospectively reviewed. Result: The peak incidence of the tumor occurred in the seventh decade of life (32.4%), There were 23 men (62.6%) and 14 women (37.8%), with mean age of 55.6 years. Twenty-six patients (70.3%) were asymptomatic and 11 patients (29.7%) had symptoms. A total of 29 tumors (78.4%) were parenchymal, and 8 (21.6%) were endobronchial. Twenty cases (54.1%) were in the right lung and 17 cases (45.9%) were in the left lung. The right lower lobe was most commonly involved. Thirty-two (86.5%) hamartomas were diagnosed by surgical resection, 4 cases (10.8%) were diagnosed by bronchoscopic biopsy and 1 case (2.7%) was diagnosed by a fine needle aspiration biopsy. Thirty-four hamartomas (91.9%) were managed by surgical resection without complication. No recurrence or malignant changes were seen during the follow up period. Conclusion: Pulmonary hamartomas are most common in males during their fifth to seventh decade and they more commonly involve the right lung. No recurrence or malignant changes were seen during the follow up period.
배경: 폐과오종은 원발성 폐종양의 $2{\sim}5%$를 차지하며, 양성 종양 중에서는 가장 흔한 형태이나, 폐과오종에 대한 임상 고찰의 국내 논문은 흔하지 않다. 대상 및 방법: 2000년 1월부터 2005년 5월까지 본원에서 조직학적으로 폐과오종이 진단된 37명의 환자를 대상으로 후향적 분석을 하였다. 결과: 발생빈도는 60대가 12예(32.4%)로 가장 많았다. 남성이 23명(62.6%)이었고, 여성이 14명(37.8%)이었으며, 평균 연령은 55.6세였다. 26명(70.3%)의 환자는 무증상이였고, 11명(29.7%)은 증상이 있었다. 29예(78.4%)는 폐실질내 과오종이였고, 8예(21.6%)는 기관지내 과오종이였다. 20예(54.1 %)가 우측폐에 발생하였으며, 17예(45.9%)가 좌측폐에 발생하였고, 우하엽이 가장 많은 빈도를 보였다. 수술적 절제로 진단 받은 환자가 32명(86.%)이었으며, 기관지 내시경과 경피적 생검이 각각 4예(10.8%)와 1예 (2.7%)였다. 34예에서 종양제거를 시행하였으며 큰 합병증은 없었다. 재발이나 악성 변화는 관찰되지 않았다. 결론: 폐과오종의 40대에서 60대의 남자에 흔하며, 우측폐에 더 빈발한다. 추적 검사기간 동안 재발이나 악성 변화는 없었다.
