Perianal cytomegalovirus ulcer in an HIV infected patient: case report and review of literature.

We report the case of a 25-year-old man with acquired immunodeficiency syndrome, presenting with perianal ulcer and diarrhea. He had positive immunocytochemical tests for Cytomegalovirus (CMV) in circulating polymorphonuclear cells (PMN). The biopsy specimen was suggestive of CMV infection, and specific immunoperoxidase for CMV antigens positively stained endothelial cells and fibroblasts. In this report we review cutaneous CMV infection in immunocompromised patients.
