A 57-year-old woman developed dysphagia 30 years after esophagectomy with partial gastrectomy and colonic interposition due to severe and extensive caustic esophageal stricture. Upper gastrointestinal endoscopy showed a lateral spreading tumor in the colonic tube with a granular surface measuring 40 mm in diameter. The lesion was removed by piecemeal endoscopic mucosal resection. Histology revealed tubular adenoma with low/high-grade dysplasia. Although colonic interposition replacement is a relatively common procedure, especially in the past, the development of adenoma or adenocarcinoma as a late complication is very rare.
