Ectopic sebaceous glands are found very rarely in the esophagus; heretofore, several cases have been reported. The sebaceous gland is originally a source of an endodermal origin; however, there have been controversies regarding whether the origin of the esophageal ectopic sebaceous gland is ectodermal or endodermal. Ectopic sebaceous glands of the esophagus usually do not cause symptoms; thus, they are often found incidentally on endoscopy for routine health screening. Endoscopic findings are characterized by single or multiple yellow patches or nodular lesions of various sizes, sometimes with small central openings. We report two cases of esophageal ectopic sebaceous glands found incidentally during endoscopy with magnifying endoscopic findings. The lesions were in the mid-esophagus and lower esophagus, respectively, and both endoscopic findings were similar as multiple yellowish patches or plaques. Magnifying endoscopy revealed the openings of the excretory ducts surrounded by circular microvessels in both cases.
异位皮脂腺在食管中极为罕见；迄今为止，已有数例相关病例报道。皮脂腺原本是内胚层起源的结构；然而，关于食管异位皮脂腺的起源是外胚层还是内胚层一直存在争议。食管异位皮脂腺通常不会引起症状；因此，它们常在常规健康筛查的内镜检查中偶然被发现。内镜检查结果的特征为单个或多个大小各异的黄色斑块或结节状病变，有时中央有小开口。我们报告两例在内镜检查时偶然发现的食管异位皮脂腺病例，并伴有放大内镜检查结果。病变分别位于食管中段和下段，内镜检查结果均相似，为多个淡黄色斑块或斑片。放大内镜检查显示，两例病例中排泄导管的开口均被环形微血管环绕。
