title: Oral hairy leukoplakia in patients without HIV: presentation of 2 new cases.
abstract: OBJECTIVE
  We report 2 cases of oral hairy leukoplakia (OHL) in patients without HIV and present a comprehensive review of OHL in HIV-negative individuals.
  
  
  METHODS
  Two cases of non-HIV-associated OHL are described. A PubMed search identified previously reported cases. The attributes of those cases were ascertained.
  
  
  RESULTS
  OHL was confirmed in both of our cases. Both patients used inhaled steroids for pulmonary disorders, and were found to have depressed levels of immunoglobulin M. Additionally, 76 cases were identified in the literature. The condition occurred in association with various medical conditions, with the majority of patients on immunosuppressant medications (67 of 76). Systemic drugs were implicated most frequently. The condition has also been reported in healthy individuals (6 of 76).
  
  
  CONCLUSIONS
  Although thought of as an HIV/AIDS-associated condition, OHL can develop in patients without HIV, including healthy individuals. There is a strong correlation between the use of immunosuppressants and development of OHL in these patients.
