Abstract
We herein report a rare case of adenocarcinoma arising in an interposed colon. A 71-year-old male underwent total thoracic esophagectomy for thoracic esophageal cancer followed by antesternal reconstruction using the right colon. Seven months later, 18F-fluorodeoxy-glucose positron emission tomography revealed increased uptake in the interposed colon. Endoscopy detected a mass 25 mm in diameter in the cecum of the interposed colon approximately 10 cm from the distal anastomosis. An endoscopic biopsy showed well-differentiated adenocarcinoma. Partial resection of the interposed colon was performed, and the patient’s postoperative course was uneventful. The patient is currently alive with no signs of recurrence three years after the final surgery. We herein report a case of primary adenocarcinoma arising from an interposed colon after esophagectomy and review the literature.
