title: [A Case of Synchronous Multiple Esophageal Cancers Composed of Squamous Cell Carcinoma and Barrett's Adenocarcinoma].
abstract: A 67-year-old man was admitted to our hospital for treatment for multiple superficial esophageal cancers. Screening upper gastrointestinal endoscopy examination revealed a superficial squamous cell carcinoma (SCC) at the middle thoracic esophagus and Barrett's epithelium and a superficial adenocarcinoma at the abdominal esophagus. We performed a subtotal esophagectomy with gastric tube reconstruction via the retrosternal route. Pathological examination revealed a Barrett's adenocarcinoma at the abdominal esophagus. Esophageal cancer is thought to be a multicentric disease, and we sometimes find multiple esophageal cancers. In Japan, most cases of multiple esophageal cancers are composed of SCCs, and the occurrence of multiple esophageal cancers composed of SCC and Barrett's adenocarcinoma is rare. In contrast, the number of the patients with Barrett's esophagus is increasing, and the number of the patients with Barrett's adenocarcinoma also seems to be on the rise. Therefore, it is important be aware of the possibility of multiple esophageal cancers composed of SCC and Barrett's adenocarcinoma while making diagnoses.
