  Fig. 1. Colonoscopy and microscopy findings. (A-C) Colonoscopy revealed a flat, irregularly marginated, and superficially elevated lesion at the mid-rectum for which a piecemeal endoscopic mucosal resection was performed; (D) Microscopy revealed dense lymphoid infiltration involving the mucosa and submucosa (hematoxylin and eosin, ×40).
