[Infectious cervical adenopathy].

Cervical adenopathy is often found on examination, but rarely causes clinical problems. If the adenopathy persists for a longer period then three to four weeks and no infectious causes are found, further investigations are needed, especially to exclude a malignancy. The chronic infectious adenopathies are discussed: mycobacterial (tuberculous and atypical), toxoplasmosis, cat-scratch disease and actinomycosis.
