Parotid enlargement due to adenovirus infection in patient with human immunodeficiency virus infection.
The authors report a case of adenovirus-induced enlargement of the parotid gland involving a patient infected with human immunodeficiency virus (HIV). Physical examination revealed good general condition, no fever and bilateral enlargement of the parotid region, which was of increased consistency and slightly tender to palpation. Histological examination of the parotid gland demonstrated a slight periductal lymphomononuclear inflammatory infiltrate with the presence of focal points of necrosis. Tests to determine the presence of fungi and alcohol-acid resistant bacilli were negative. Immunohistochemistry for cytomegalovirus, herpes simplex, HIV p24 antigen and adenovirus showed positivity only for adenovirus in the epithelial nuclei of numerous gland ducts. This is the third case of this type reported in the literature, indicating the importance of including adenovirus in the differential diagnosis of this condition.
