A case of mucoepidermoid or adenosquamous carcinoma arising from the mucous epithelium of a Barrett's esophagus is presented. Immunohistologic examination demonstrated carcinoembryonic antigen (CEA) in both the glandular and squamous components, but keratin only in the latter. Although mucoepidermoid carcinoma of the esophagus is believed to arise from submucosal glands, heterotopic gastric surface epithelium may also give rise to this uncommon neoplasm.
本文报告1例起源于巴雷特食管黏液上皮的黏液表皮样癌或腺鳞癌。免疫组织学检查显示，癌胚抗原（CEA）在腺性和鳞状成分中均有表达，但角蛋白仅在鳞状成分中表达。尽管食管黏液表皮样癌被认为起源于黏膜下腺体，但异位的胃表面上皮也可能引发这种罕见肿瘤。
