Abstract

Depressed-type duodenal adenoma is rare. We report a case of 51 year-old man with this disease. An upper gastrointestinal endoscopy examination for health screening revealed a depressed lesion, 3 mm in diameter, in the second portion of the duodenum. We suspected the lesion was adenoma or carcinoma limited in the mucosal layer by endoscopic findings. We removed this lesion by endoscopic mucosal resection (EMR). Pathological findings of the resected specimen showed a depressed lesion, 3 mm in diameter, and the histology of the depressed lesion was tubular adenoma with moderate atypia. EMR can be applied for the diagnosis and treatment of duodenal neoplasms under cautious performance.
