[Intraparotid lymphoepithelial cysts and the human immunodeficiency virus]. / Quistes linfoepiteliales intraparotídeos y virus de la inmunodeficiencia humana.

Lymphoepithelial lesions in the parotid gland are an uncommon benign entity, with an increasing incidence since 1980 due to the involvement of HIV infected patients. We report here three cases recorded at the ORL service in Viladecans Hospital, with cytologic investigation with echo-guided fine needle aspiration. A discussion follows on the theory that these cysts are part, together with persistent polyadenopathies, of the immune response to HIV infection. The course towards malignancy is exceptional and conservative management is most accepted.
