Abstract:
A 73-year-old man who was being treated with corticosteroids for nonsystemic vasculitic neuropathy developed small-bowel hemorrhage after ileostomy for ileus. Immunohistochemical staining for cytomegalovirus (CMV) antigen in the ulcer in the resected ileum was positive; thus, cytomegalovirus infection of the small intestine caused his gastrointestinal manifestations. Cytomegalovirus infection should be considered in the differential diagnosis of gastrointestinal diseases in patients with collagen vascular diseases receiving immunosuppressive agents.
