case_images: Subsequent endoscopy demonstrated a narrow distal rectum, with the overlying mucosa being indurated, non-ulcerated, with a cobblestone appearance (Fig. 1).

case_images: Transrectal ultrasonography showed circumferential infiltration of the submucosa, whereas the other layers were normal (Fig. 2); an image compatible with "linitis plastica".

case_images: Macroscopic examination of a sagittal section of resected rectum demonstrated an expanded submucosal layer due to infiltration with cancer cells, with intact mucosa and muscular layer (Fig. 3).
