case_images: CT scan of the abdomen and pelvis showed pericecal inflammatory stranding without pneumatosis concerning cecal typhlitis as well as an "apple-core mass" of the ascending colon near the hepatic flexure concerning colon cancer (Figure 1).
case_images: Colonoscopy showing a mass in the proximal transverse colon. Mucosa presents with nodularity, loss of vascular pattern, and diffuse exudates.

case_images: It revealed diffuse friable changes of the colonic wall extending from the cecum to the hepatic flexure and the transverse colon (Figure 2).
case_images: H&E, 126x magnification, showing changes of chronic, active colitis including crypt architectural distortion (branching) and focal active cryptitis (white arrow).

case_images: Final pathology from the cecal biopsy specimens showed chronic active colitis with cryptitis, ulceration, and architectural distortion (Figure 3).
case_images: (a) CMV immunohistochemical stain, 200x magnification, highlighting both nuclear and cytoplasmic staining (brown chromogen) within the ulcerated granulation tissue. (b) H&E stain, 400x magnification, showing a CMV-infected endothelial cell with dot-like cytoplasmic inclusions (white arrow).
