Classification and diagnostic criteria for oral lesions in HIV infection. EC-Clearinghouse on Oral Problems Related to HIV Infection and WHO Collaborating Centre on Oral Manifestations of the Immunodeficiency Virus.

A consensus has been reached on the classification of the oral manifestations of HIV infection and their diagnostic criteria, based on presumptive and definitive criteria. The former relate to the initial clinical appearance of the lesion and the latter are often the result of special investigations. Candidiasis, hairy leukoplakia, specific forms of periodontal disease [linear gingival erythema, necrotising-(ulcerative) gingivitis and necrotising(ulcerative) periodontitis], Kaposi's sarcoma and non-Hodgkin's lymphoma are strongly associated with HIV infection. Lesions less commonly associated with HIV infection and lesions seen in HIV infection, but not indicative of the disease, are also listed.
