Chronic lymphadenitis
Chronic lymphadenitis is often secondary to inflammatory lesions in the head, face, and neck. Lymph nodes swell to varying degrees and are scattered in the lateral neck area or submandibular and submental areas. They may be slightly hard but smooth in surface and can move, with mild tenderness or discomfort. Chronic lymphadenitis does not require treatment, but care should be taken to find the primary inflammatory focus during the examination. In addition to the various areas of the neck, the scalp, external ear, oral cavity, tonsils, gums and other hidden areas should also be carefully examined. The primary lesion can also be found according to the lymph node receiving area of the swollen lymph nodes.
