起源于异位胃粘膜的上段食管腺癌国内文献尚未见报告、国外亦属罕见,现报告1例并结合有关文献进行讨论。 患者男,52岁,咽部紧缩感6个月,于1986年2月就诊,余无其他明显症状。体验各系统未发现器质性病变。食管钡片示主动脉弓上缘5cm管壁僵硬,粘膜中断,管腔无狭窄。内镜检查距门齿22～28cm的食管粘膜呈颗粒状改变,管壁扩张度好,28cm以远区域食管粘膜正常。病灶活检为腺癌。全身重要脏器功能检查除HBs Ag阳性外均未见异常。遂于1986年12月于全麻下经左胸探查食管、病灶主要位于主动脉弓上, The domestic literature of the upper esophageal adenocarcinoma originating from the ectopic gastric mucosa has not been reported yet, and it is also rare in foreign countries. One case is reported and discussed in conjunction with related literature. The patient male, 52 years old, had a tight throat sensation for 6 months. He was seen in February 1986 and had no other obvious symptoms. No organic disease was found in each system. The esophageal septum showed that the wall of the upper edge of the aortic arch was stiff and the mucosa was interrupted. There was no stenosis in the lumen. Endoscopic examination of the esophageal mucosa from 22 to 28 cm in front of the incisor changes in a granular manner, with a good dilation of the vessel wall, and the esophageal mucosa is normal at a distance of 28 cm. The lesion biopsy was adenocarcinoma. Except for HBsAg positive, no significant abnormalities were found in vital organ function tests. In December 1986, under general anesthesia, the left chest was used to probe the esophagus and the lesion was mainly located on the aortic arch.
