Host pathogen interaction and the development of oral lesions.
The aetiologies of oral ulceration, disseminated interstitial lymphocytosis syndrome and oral lymphomas have been reviewed, with emphasis on the role of HIV infection in the primary causation or modification of the presentation of these entities. There is a paucity of evidence to explain why oral ulceration is so severe in HIV infection, and why major ulceration affects the oropharynx. A number of mechanisms have been proposed to account for the development of lymphomas in patients with HIV infection, including a genetic predisposition, decreased immunosurveillance due to HIV infection, alteration of endothelial cell function and dysregulation of cytokine networks. From this review, it was concluded that there is a need for a prospective multicentre study, to elucidate the aetiological mechanisms involved in lymphomas of the oral regions in this patient group. It was concluded that, although there is anecdotal evidence implicating tobacco use in the aetiology of the lesions reviewed, this is insufficient to allow definitive statements to be made and further systematic evaluation is indicated.
