We describe a rare case of cervical esophageal adenocarcinoma originating from the esophageal gland. A 63-year-old man underwent endoscopic screening during a medical checkup, during which a type 2 tumor was incidentally detected in the cervical esophagus, which was confirmed as adenocarcinoma on biopsy. Endoscopic ultrasonography indicated that the tumor had invaded the muscularis propria layer. Computed tomography and 18F-fluorodeoxyglucose positron emission tomography imaging revealed neither lymphadenopathy nor distant metastasis. He was clinically diagnosed with T2N0M0, Stage Ⅱ disease. He preoperatively received 2 courses of chemotherapy consisting of cisplatin (90mg/m2) on day 1 and 5-fluorouracil (900mg/m2) on days 1‒5. Esophagectomy with lymph node dissection was performed. Histopathological diagnosis showed well-differentiated tubular adenocarcinoma that probably originated from the ducts of the esophageal glands. The final diagnosis was T1bN0M0, Stage I disease. The postoperative course was uneventful. He was healthy without any recurrence 27 months after the surgery.
