Kaposi's sarcoma of the parotid gland in acquired immunodeficiency syndrome.

A patient with acquired immunodeficiency syndrome complained of a dry mouth and bilateral swelling of the parotid glands. Kaposi's sarcoma (KS) was found within the tissue of the parotid gland. Although KS is a common manifestation of acquired immunodeficiency syndrome, the presence of KS in the salivary glands is very rare. The human immunodeficiency virus I (HIV-I) genome was not identified in parotid glandular cells or in KS cells in this case, although the virus was detected in infiltrating lymphocytes and in tissue macrophages.
