title: Nodular colitis: endoscopic image an unusual finding.
abstract: An 82-year-old male with a history of high blood pressure, COPD, chronic myeloid leukemia, and stage-4 chronic renal failure. Admitted to hospital for lower-limb cellulitis and severe COPD exacerbation, he received antibiotic therapy and bronchodilators. During his hospital stay he developed severe anemia and had an hematochezia event with no diarrhea. A complete colonoscopy found small (4-7 mm) nacreous elevated lesions, circumferential in shape, in the cecum and ascending colon with some bleeding stigmata and submucosal bleeding suggestive of infectious colitis; stool culture was negative and Clostridium difficile toxins were positive. The condition was histologically confirmed.
