Inlet patches (IP) are heterotopic lesions consisting of gastric mucosa. Commonly located in the cervical esophagus, it is believed that they are remnants of fetal columnar epithelium arising from incomplete replacement during embryogenesis. A rare complication of IP is the development of proximal esophageal adenocarcinoma. We report a case of a 59-year-old male with intractable cough and dysphagia that was found to have a malignant transformation of an IP.
入口斑（IP）是由胃黏膜构成的异位病变。通常位于颈段食管，据信它们是胚胎发育过程中由于不完全替代而产生的胎儿柱状上皮的残余物。IP的一种罕见并发症是近端食管腺癌的发生。我们报告一例59岁男性，有顽固性咳嗽和吞咽困难，经检查发现其入口斑发生了恶性转化。
