초록
식도의 평활근종은 대개 무증상을 보이며 상부 내시경검사 중 우연히 발견되는 경우가 많다. 식도 평활근종과 편평상피세포암이 동일부위에 공존하는 경우는 국내 문헌에 매우 드물게 보고되고 있으며, 이들의 연관성은 아직까지 분명하게 밝혀지지 않았다. 또한 식도 평활근종과 동반된 편평상피세포암을 내시경 점막절제술로 제거된 예는 아직 국내에서 보고된 바 없다. 저자들은 우연히 발견된 표재성 식도암과 그 하부에 발생한 식도 평활근종을 내시경 점막절제술로 동시에 성공적으로 치료하였기에 보고하는 바이다.
Abstract
The coexistence of esophageal submucosal tumors and carcinomas is rare and the association between them is still unclear. Here, we report a case of a superficial esophageal carcinoma that developed over an esophageal leiomyoma, which was removed successfully by an endoscopic mucosal resection. A 76-year-old man was admitted for the treatment of an esophageal carcinoma. The endoscopic examination revealed a 1 cm-sized round, flat, elevated lesion located at the 25 cm mark of the endoscopy. Endoscopic ultrasonography revealed the carcinoma to be limited to the mucosal layer. Interestingly, a 1.2 cm sized, hypoechoic, subepithelial mass was present beneath the carcinoma. An endoscopic resection was performed simultaneously using a suction and snaring method with a transparent cap attached to the tip of the endoscope. A histopathology examination revealed a squamous cell carcinoma restricted to the mucosa immediately over the benign leiomyoma arising from the muscularis mucosa. The patient has remained well during 1 year follow-up period and has shown no evidence of recurrence. (Korean J Gastrointest Endosc 2007;34:324-328)
