Cytomegalovirus colitis manifested with a ring like ileocecal valve ulcer in a Korean AIDS patient.

A 32-year-old man, who had no previous medical history, was hospitalized with 3-week duration of abdominal pain, fever, and watery diarrhea. Initial colonoscopy showed subepithelial hemorrhagic spots throughout the entire colon together with well-circumscribed ulcer around the ileocecal valve. Serologic test disclosed HIV-positive and repeated biopsies at ulcer base finally revealed that the patient had cytomegalovirus ulcer in ileocecal area.
