Oral hairy leukoplakia in a patient with ulcerative colitis.
A 30-year-old man with ulcerative colitis developed oral hairy leukoplakia (OHL). Serological examination for human immunodeficiency virus (HIV)-1 and HIV-2 infection showed no abnormalities. Biopsy specimen of the lateral tongue showed ballooned prickle cells, and electron microscopy revealed herpes-type viruses. Immunologic investigation of the patient showed a marked decrease in T-helper cells as a result of immunosuppressive regimen. The present report appears to be the first well-documented case of OHL in an HIV-negative patient with ulcerative colitis. OHL may be a marker for severe immunosuppression but is not necessarily associated with HIV infection. Patients with iatrogenic immunosuppression should be monitored for OHL. Concerning the marked decrease in T-helper cells in this case, the presence of OHL may imply the examination of T-lymphocyte subsets in patients such as HIV-infected individuals or in organ transplant recipients.
