Abstract Chronic enlargement of salivary glands and mainly of parotid glands has been noted in HIV-positive patients. Such alterations are due mainly to adenopathies (mainly intraglandular) or to the formation of lymphoepithelial cysts. During the period between January 1990 to June 1993 we studied 63 HIV-positive patients with enlargement (mainly monolateral) of the parotid glands and one patient with involvement of the submandibular gland. There were 59 adults (44 males and 15 females) 22–50 years of age, and five children 3–8 years. The fastest, least expensive and most appropriate investigative means for this pathology is echography, which was carried out in all patients. Only 18 patients were also studied with CT. We observed lymphadenopathies within or outside the parotid glands and lymphoepithelial cysts. Within some intraparotid cysts we observed an ultrasonographic pattern consisting of small high-level formations in suspension which, from cytologic evaluation of material obtained by needle aspiration, were referable to small crystals of calcium oxalate. We hypothesize that such microcalculi may play a role in the obstructive mechanism of the ducts in association with lymphoepithelial infiltration of the parotid ducts.
