Four HIV-positive patients with herpes simplex virus and cytomegalovirus coinfected oral ulcers are presented. All patients had persistent oral pain associated with nonhealing mucosal ulcers. Lesions occurred on the palate, retromolar pad, tongue, and lip, and the clinical appearance of the ulcers was nonspecific. Histologic and immunohistochemical stains showed herpes simples virus alterations in keratinocyte nuclei and cytomegalovirus alterations in mesenchymal/endothelial cell nuclei and cytoplasm. Lesions in one patient responded to ganciclovir therapy. One patient improved with acyclovir, and another healed normally after excisional biopsy. Each virus alone has been described as causing oral ulcerations; their appearance together in the same lesion would suggest a synergistic relationship.
