case_images: EGD revealed severe diffuse hemorrhagic gastritis (Figure 1) with biopsies consistent with chronic gastritis and no malignant features.
case_images: Severe colitis localized at the cecum with friable mucosa.

case_images: Colonoscopy showed localized, severe colitis at the cecum that was erythematous, friable, and ulcerative (Figure 2).
case_images: Extraluminal compression and protruding ileocecal valve resulting in narrowing of cecal lumen.

case_images: There was also extraluminal compression of the cecum with protrusion of the ileocecal valve and luminal narrowing (Figure 3).
case_images: Circumferential cecal mass resulting in narrowing of the terminal ileum and cecal lumen.

case_images: fig4
case_images: This ultimately revealed a cecal mass measuring 12 x 12 x 4.7 cm with the bulk of the mass protruding into the terminal ileum causing high-grade narrowing of the lumen (Figure 4). Lymphadenopathy was localized to the right lower quadrant, and no distant lymphadenopathy was observed elsewhere (Figure 4).
case_images: H&E stain showing normal colonic mucosa on the right and small lymphoma cells on left. Cyclin D1+, CD5+ (weak), K67~68%.
