The occurrence of an esophageal inlet patch of gastric mucosa in Japan is 4.0% in males and 2.6% in females, most of which are reported to be located near the esophageal inlet patch. However, the number of the cases of adenocarcinoma developing from an inlet patch reported in Japan is only 5, as a for as we know, and its occurrences quiterare. Here, we report a case of a 74-year-old woman who had no particular past history or familial history. She had an episode of upper abdominal discomfort on December 27, 1993, and was admitted to our hospital for examination on January 17, 1994. Upper gastrointestinal X-ray examination showed a pediculate tumor of 3 cm in the cervical esophagus. Upper gastrointestinal endoscopy revealed a polypoid lesion of Yamada Type III in the left side of the posterior wall of the cervical esophagus, about 14 cm from the teeth. Biopsy was performed and it was revealed to be a papillary adenocarcinoma. The depth of this tumor was considered from endoscopic ultrasonography to reach the muscular layer of the mucosa. Resection of the mucosa of the cervical esophagus including the tumor was performed on February 15, 1994. Its histology revealed the tumor be a well-differentiated adenocarcinoma of the esophagus developing from an inlet patch of gastric mucosa. Here, we report this quite rare case of early adenocarcinoma of the cervical esophagus with a brief review of the literature.
