Abstract

Background : Pulmonary hamartomas are the most common form of benign tumors, occurring in approximately 0.2% of routine autopsies. However, only a few reports on the clinical characteristics of pulmonary hamartoma in Korea have been published. Materials and Methods : The charts, X-rays and pathological specimens of 29 pulmonary hamartoma patients who were diagnosed by a pathological examination from 1990 to 1999 at the Catholic Medical Center were retrospectively reviewed. Results : The peak incidence of the tumor occurred in the sixth decade of life (37.5%). Seventeen patients (58.6%) were asymptomatic and 12 patients (41.4%) had symptoms. Chest discomfort was the most common symptom (31.0%). A total of 25 tumors (86.2%) were parenchymal, and 4 (13.8%) were endobronchial. Twenty cases were in the right lung and 9 cases were in the left lung (approximately 1:2.2). The RLL was the most commonly involved lobe (31.0%). Calcification was noted in 5 cases(19.2%) on a plain X-ray and in 5 cases (29.4%) on chest CT. Accompanied neoplasms were observed in 2 cases. Twenty-four hamartomas (82.8%) were diagnosed by a surgical resection and 4 cases(13.8%) were diagnosed by a fine needle aspiration biopsy. Twenty-six hamartomas (89.7%) were managed by a surgical resection. The follow up ranged from 4 to 55 months (mean, 19.6 months) and no recurrent pulmonary hamartomas were noted. Conclusion : Pulmonary hamartoma is more common in females and more commonly in the right lung. Calcification was noted only in 19.2% on a plain chest X-ray and 29.4% on a chest CT. No recurrent hamartomas had developed during the follow up period.

연구배경 : 폐과오종은 폐에 발생하는 양성 종양중 가장 흔한 형태의 종양이다. 하지만 아직 국내에 폐과오종에 대한 논문은 그리 많이 발표되어 있지 않다. 방 법 : 저자들은 1990년에서 1999년까지 가톨릭대학교 성모병원, 강남성모병원, 성바오로병원, 성빈센트병원에서 조직학적으로 폐과오종으로 진단받은 환자를 대상으로 후향적인 분석을 시행하였다. 결 과 : 위의 기간동안 폐과오종을 진단받은 환자는 29명이었다. 발생빈도는 50대가 11명 (37.5%)로 가장 많았다. 증상이 있었던 경우는 12명 (41.4%)로 흉부불쾌감이 가장 흔한 증상(31.0%) 이었으며 무증상이 경우는 17례 (58.6%)였다. 폐내과오종이 25예 (86.2%)로 기관지내 과오종의 4예(13.8%)에 비해 많았으며 좌측폐에 발생한 경우보다 우측폐에 발생한 경우가 많았다(1:2.2). 석회화소견은 단순 X-선상 19.2%에서, 흉부컴퓨터단층촬영상 29.4%에서 관찰되었다. 수술적절제로 진단받은 경우가 24예 (82.8%)로 대부분을 차지했으며 경피폐생검에 의해 진단된 경우는 4예(13.8%)였다. 26예 (89.7%)에서 수술적 절제술을 시행하였고 3예에서는 추적관찰만을 시행하였다. 평균 19.6개월의 추적기간중 재발한 예는 없었다. 결 론 : 폐과오종은 남성보다 여성에서 보다 많이 관찰되었으며 좌측보다는 우측에서 발생한 경우가 많았다. 석회화 소견은 흉부 X-선상 19.2%, 흉부컴퓨터단층촬영상 29.4%에서만이 관찰되었다, 추적관찰기간 동안 재발된 예는 없었다.
