Oral lesions often occur in HIV and are reflections of reduced immune function manifested as oral opportunistic conditions, which are often the earliest clinical features of HIV infection. Some, in the presence of known HIV infection, are highly predictive of the ultimate development of the full syndrome, whereas others represent the
Oral lesions seen in association with HIV infection are classified in Table 12-1, and our general approach to the diagnosis and management of oral HIV disease is summarized in Table 12-2. Standardized definitions and
Candidiasis
The pseudomembranous form of oral candidiasis (thrush) was described in the first group of AIDS patients and is a harbinger of the full-blown syndrome in HIV-seropositive individuals. We have shown that both oral candidiasis and hairy leukoplakia predict the development of AIDS in HIV-infected patients independently of

Unusual forms of gingivitis and periodontal disease are seen in association with HIV infection. The gingiva may show a fiery red marginal line, known as linear gingival ethema, even in mouths showing absence of significant accumulations of plaque. The periodontal disease, necrotizing ulcerative periodontitis, occurs in approximately
Other Bacterial Lesions
A few cases have occurred of oral mucosal lesions associated with unusual bacteria, includ-ins Klebsiella pneumoniae and Enterobacter cloacae. These have been diagnosed using aerobic and anaerobic cultures and
Herpes Simplex
Oral lesions due to herpes simplex virus (HSV) are a common feature of HIV infection. The condition usually occurs as recurrent intraoral lesions with crops of small, painful vesicles that ulcerate. These lesions commonly appear on the palate or gingiva. Smears from the lesions may reveal giant cells, and HSV can be identified
Herpes Zoster
Both chickenpox and herpes zoster (shingles) have occurred in association with HIV infection. In orofacial zoster, the vesicles and ulcers follow the distribution of one or more branches of the trigeminal nerve on one side. Facial nerve involvement with facial palsy (Ramsay Hunt syndrome) also may occur. Prodromal
Cytomegalovirus Ulcers
Oral ulcers caused by cytomegalovirus (CMV) occasionally occur. These ulcers can occur on any oral mucosal surface, and diagnosis is made by biopsy and immunohistochemistry. Oral ulcers due to CMV are usually seen
Hairy Leukoplakia
First seen on the tongue in homosexual men, hairy, leukoplakia has since been described in several oral mucosal locations, including the buccal mucosa, soft palate, and floor of mouth and in all risk groups for AIDS. Hairy, leukoplakia
produces white thickening of the oral mucosa, often with vertical folds or corrugations
Warts
Oral lesions caused by human papillomavirus (HPV) can occur as single or multiple papilliferous warts with multiple white and spike-like projections, as pink cauliflower-like masses , as single projections, or as flat lesions resembling focal epithelial hyperplasia. In patients with HIV infection, we have seen numerous examples
If large, extensive, or otherwise troublesome, these oral warts can be removed using surgical or laser excision. In some cases, we have seen recurrence after therapy and even extensive spread throughout the mouth.
Neoplastic Disease
Kaposi's Sarcoma
Kaposi's sarcoma (KS) in patients with AIDS produces oral lesions in many cases. The lesions occur as red or purple
macules, papules, or nodules. Occasionally, the lesions are the same color as the adjoining normal mucosa. Although frequently they are asymptomatic, pain may occur because of traumatic ulceration with inflammation
Lymphoma
Although not seen as frequently as with oral KS, oral lesions are a common feature of HIV-associated lymphoma. A biopsy may prove that poorly defined alveolar swellings or discrete oral masses in indiv4duals
Carcinoma
Several cases have been seen of oral squamous cell carcinoma, particularly of the tongue, in young homosexual males. It is not clear whether these lesions are related to HIV infection; population-based and
Other Lesions
Recurrent aphthous ulcers (RAU) are a common finding in the normal population. There is an impression, not as vet substantiated by prospective studies of incidence, that RAU are more common among HIV-seropositive individuals. These lesions occur as recurrent crops of small (1- to 2-mm) to large (1-cm) ulcers on the
