[A cystic lymphoepithelial lesion of the parotid in HIV-1-infected patients].

: Cystic lymphoepithelial lesion is an infrequent disorder involving the saliva glands mainly the parotid gland; however, its frequency has increased coinciding with the epidemics of HIV-1 infection. Three cases of parotid lymphoepithelial lesion in patients with HIV-1 infection, 2 of whom were hemophiliacs and one an ex-intravenous drug addict, are presented. In all the cases the lesion was a painless slow growth right submandibular mass, with no history of inflammation. Two of the patients had a contralateral tumor of the same characteristics which was not studied. Fine needle aspiration puncture was performed in the three patients although diagnosis was obtained by pathologic study following superficial parotidectomy. Cystic lymphoepithelial lesion is an entity to be taken into account on differential diagnosis of cervical masses in patients with HIV infection. In individuals with severe immunosuppression treatment should be conservative.
