Computed tomography of the abdomen and pelvis with oral and intravenous contrast
                    revealed innumerable polypoid filling defects within the transverse and
                    descending colon.

Computed tomography of the abdomen and pelvis with oral and intravenous                 contrast revealed innumerable polypoid filling defects within the transverse and                 descending colon (Fig. 1).                 Sigmoidoscopy revealed innumerable polyps in the rectum and sigmoid colon with a                 large mass (5.0 cm by 2.0 cm) in the sigmoid colon (Figs. 2 and 3).
Sigmoidoscopy revealed innumerable polyps in the rectum and sigmoid colon.

Sigmoidoscopy revealed innumerable polyps in the rectum and sigmoid colon with a                 large mass (5.0 cm by 2.0 cm) in the sigmoid colon (Figs. 2 and 3).
Biopsy of the mass revealed a moderately differentiated adenocarcinoma
                        (A) invading the subserosa (B).
                    Immunohistochemistry staining revealed homogenous proliferative activity with
                    ki-67 (C) and variable intensity P53 staining (D).

Biopsy of the mass revealed a moderately                 differentiated adenocarcinoma (Fig.                     4A) invading the subserosa (Fig. 4B). Immunohistochemistry staining revealed homogenous                 proliferative activity with ki-67 (Fig.                     4C) and variable intensity P53 staining (Fig. 4D).
Endoscopy revealed innumerable polyps and "coffee ground" blood
                    in the fundus, body, and cardia of the stomach.

The tumor was                 classified as MSI-High, indicating a high probability of microsatellite instability.                 Endoscopy revealed innumerable polyps and "coffee ground" blood in                 the fundus, body, and cardia of the stomach (Fig. 5).
