Swollen preauricular lymph nodes are a common, non-specific clinical condition that can be caused by a variety of diseases, usually triggered by infectious diseases or lymphoma.
AIDS, or acquired immunodeficiency syndrome, is caused by infection with the AIDS virus (HIV). Some patients present with persistent and widespread generalized lymph node enlargement, especially in the neck, axillae and groin. Patients with multiple swollen lymph nodes and a history of HIV exposure should be on high alert and should undergo further testing.
