Abstract

An esophageal submucosal gland duct adenoma is a rare benign disease. We report a 58-year-old man who presented with an esophageal submucosal tumor on health screening endoscopy. The endoscopic examination showed a round elevated lesion with central depression at the mid-esophagus. On endoscopic ultrasonography, an anechoic lesion with some hyperechoic septal structures measuring 8 mm in the largest diameter was observed in the third layer. We resected the lesion endoscopically. Histologically, there were several dilated gland ducts, with proliferation of the inner epithelial and outer myoepithelial cell layers. These findings were compatible with a submucosal gland duct adenoma of the esophagus.

식도 점막하 도관 선종은 드문 질환으로 대부분의 식도 선종과는 달리 바렛식도 없이 식도 고유선에서 발생한다. 위내시경을 통한 육안적 검사로는 감별진단이 어려우며 내시경 초음파에서 낭종 외벽이 두껍거나 낭종내 격막이 관찰되면 의심해 볼 수 있다. 특징적인 조직소견은 낭종 내부 도관 상피세포와 외부 근 상피세포로 이루어진 두층 구조를 가진 조직이 증식한다는 점이다. 본 증례는 건강검진에서 우연히 발견된 식도 점막하 병변을 내시경적 절제술을 시행하여 도관 선종을 진단하였고 국내에 보고된 바 없어 문헌고찰과 함께 보고하는 바이다.
