[Benign parotid lymphoepithelial cysts associated with HIV infection].

HIV infections are often related with lymphoepithelial benign cysts of the parotid gland; these lesions are uncommon and other salivary glands are rarely involved. The diagnosis, often difficult, is based on imaging techniques, like computed tomography, and pathologic techniques, like fine needle aspiration biopsy. The therapeutic approach can be performed by simple aspiration, surgical resection, pharmacotherapy, or radiotherapy. Three cases of HIV-related lymphoepithelial benign cysts of the parotid gland observed at the Department of Maxillofacial Surgery of the "Federico II" University of Naples and at the Department of Oral and Maxillofacial Surgery of "La Paz" Hospital of the Universitad Autonoma of Madrid are described.
