Ischemic colitis of the cecum after renal transplantation masquerading as malignant disease.
Fourteen years after kidney transplantation and following protracted rejection of the transplant, a patient developed abdominal pain, fever, and leukocytosis. Ultrasound demonstrated a pericolic abscess, and barium enema a deformity of the ascending colon suggesting malignant growth. Colonoscopy showed ulcerative and necrotic lesions of the cecum, and colonic carcinoma was suspected. At surgery, a granulomatous inflammatory reaction with fibrosis involving the kidney transplant and cecum was found. Histological examination revealed ulcerations secondary to ischemic colitis, but no malignancy. Thus, ischemic colitis should be ruled out in cases with a presumptive diagnosis of colonic malignancy at x-ray or endoscopy.
