Adenovirus parotitis in patients with AIDS.

Adenoviruses are well documented as opportunistic pathogens in patients with immunocompromising conditions, including human immunodeficiency virus (HIV) infection. We recently diagnosed adenovirus infection of the parotid gland in two patients with AIDS. Viral cultures and electron microscopic examinations of parotid tissue were positive in both cases. Adenovirus infection should be considered in the differential diagnosis of parotid swelling in HIV-infected patients.
