[A Case of Colon Cancer That Developed in the Subcutaneously Reconstructed Colon after Esophagectomy for Thoracic Esophageal Cancer].

An 83-year-old man with a history of esophagectomy for thoracic esophageal cancer presented with a chief complaint of upper gastrointestinal endoscopy abnormality. Upper gastrointestinal endoscopy revealed colon cancer developing in the subcutaneously reconstructed colon, located 45 cm from the incisor tooth. Computed tomography and positron-emission tomography revealed a thickening of the wall of the reconstructed colon, a lymph node metastasis adjacent to the reconstructed colon, and no distant metastases. A partial colectomy with excision of the breastbone, rib cartilage, and the lymph node adjacent to the reconstructed colon was performed. The patient experienced a localized recurrence on postoperative day 75 and was treated with chemotherapy. The patient is alive 2 years after the diagnosis of local recurrence.
