 AB    Benign lymphoepithelial cysts (BLC) are rare disorders of salivary
       glands (0.6%). In patients infected by HIV, they are seen more often. In
       comparison to sporadic BLC, the patients are younger, the diameter of
       the cysts is up to 5 cm and they are often located bilaterally. At the
       Department of ENT, Head and Neck Surgery of the
       Ludwig-Maximilians-University, Munich, ten HIV-infected patients (two
       females) showed lymphoepithelial cysts (six times bilaterally). One of
       these revealed a metastasis of a small cell neoplasma near the cysts,
       another patient showed a non-Hodgkin's lymphoma of low grade malignancy
       (MALT-type), and one patient additionally had bilateral Warthin's
       tumours. The BLCs were mostly located in the parotid tail. In three
       cases, the cysts were found on the inferior border of the parotid and
       once at the submandibular gland. The age ranged from 27 to 71 years
       (medium 45.7 years). The mode of HIV infection was homosexuality five
       times, drug abuse twice, heterosexuality once, and blood products once.
       In two cases, the channel of transmission was unknown. The majority of
       the patients showed minor HIV illness (CDC II [n = 2]/CDC III [n = 4]);
       the rest had advanced immunodeficiency (CDC IV [n = 4]). All the cysts
       were examined by ultrasonography and NMR. According to the clinical
       findings and the general stage of health, BLCs were either enucleated (n
       = 8) or a superficial parotidectomy (n = 5) and selective biopsy of
       lymph nodes (n = 3) suspected to be malignant were performed.(ABSTRACT
