초록

폐장은 신장세포암의 흔한 전이 장기 중 하나이지만 기관지내 전이는 매우 드물다. 저자들은 신장세포암이 기관지내로 전이한 환자를 수술하였기에 보고한다. 8년전 신장세포암으로 좌측 신장 적출술을 받은 63세 남자가 반복적인 기침을 주소로 내원하였다. 흉부 컴퓨터 단층촬영과 기관지 내시경 검사에서 좌하엽 기관지로부터 이차 기관 분기부까지 자라는 폴립모양의 기관지내 종양이 발견되었고 생검 결과는 만성 염증 소견과 함께 괴사성 조직으로 진단되었다. 수술 중 종괴의 냉동 절편 조직검사에서 전이성 신장세포암으로 확인되었고 상부의 좌하엽 기관지의 점막 침윤이 없어서 좌하엽 절제술과 림프절 청소술을 시행하였다. 치종 병리학적 검사에서도 전이성 신장세포암으로 확진되었고 림프절 전이는 없었다. 환자는 수술 후 10일째 특별한 합병증이 없이 퇴원하였다.

Lung parenchyma is a common organ for metastases of extrathoracic tumors, but endobronchial metastasis is very rare. In this report, we present a case of endobronchial metastases from renal cell carcinoma (RCC), and this was managed by performing operative resection. A 63-year-old man presented with frequent dry cough; he had previously undergone left nephrectomy and postoperative chemotherapy for grade 2 RCC eight years ago. Computed tomography and bronchoscopy showed an endobronchial tumor from the left lower lobe bronchus to the second carina, and this mass was diagnosed as a necrotic tissue with chronic inflammation at biopsy. During the operation, the mass was revealed to be a metastatic renal cell carcinoma on the frozen section diagnosis and there was no mucosal invasion on the resection margin of the left lower lobe bronchus. We performed lobectomy of the left lower lobe with systemic dissection of the mediastinal lymph nodes. The final histopathologic diagnosis of the endobrochial mass was metastatic RCC and any mediastinal lymph node metastasis was not found. The patient was discharged on postoperative day 10 without any postoperative complications.
