摘要：
A 72-year-old woman with an unremarkable medical history underwent an upper gastrointestinal endoscopy in May 2002 because of dyspepsia. An examination showed a pedunculated polyp lesion in an inlet patch on the posterior wall of the esophagus, 20∈cm distant from the incisors and measuring 1.5∈cm. Forceps biopsies were obtained, and the pathological analysis showed a gastric-like mucosa with well-differentiated pyloric glands below an atrophic squamous epithelium; most of the glands were lined with atypical cells, compatible with low-grade dysplasia. Histological examination after endoscopic removal showed a low-grade dysplasia in an adenomatous polyp of the esophagus developing on pyloric-type heterotopic gastric mucosa (HGM). Three years later, the patient remains well with no evidence of esophageal disease. We review 25 reported cases of adenocarcinoma and 3 cases of high-grade dysplasia arising in HGM. © Japan Esophageal Society and Springer-Verlag 2005.
