Linear gingival erythema in an HIV-seropositive man.

Linear gingival erythema (LGE) is part of the spectrum of periodontal disease that exists in the HIV-infected population. Here, a typical case of LGE is presented and described. The microbiology and therapeutics of LGE are discussed, as well as this condition's relationship to more severe, rapidly destructive infectious diseases--such as necrotizing ulcerative periodontitis and necrotizing stomatitis.
