The second hospital of Shandong University pediatric surgery Li Jinliang: Lymph node enlargement can be considered in three cases: generally lymph node reactive enlargement, hyperplasia or enlargement, secondary to inflammation of lymph nodes or areas drained by lymph node groups, such as pharyngitis, tonsillitis causing cervical lymph node enlargement, inflammation of the mouth, lips and gums causing submandibular lymph node enlargement, scalp boils, folliculitis, prickly heat infection causing postoccipital, postauricular or cervical lymph node enlargement. Such enlargement usually shrinks with the healing or cure of the corresponding inflammation and the pain disappears without further treatment, but the enlarged lymph nodes will not be small enough to be felt in the short term. This is a normal response of the body to inflammation, unless the area from which it drains has not been inflamed for several years. The second common case is the above-mentioned secondary lymph node enlargement or lymphadenitis in which the lymph nodes continue to be enlarged, red, painful, or even feverish and abscess formation at the same time as the primary inflammation or after healing, which should be treated for lymphadenitis. Third, the rare case of unexplained lymph node enlargement, no redness, swelling, heat and pain, no fever, generally larger than the lymph nodes to form lumps, we should suspect blood diseases or other malignant diseases caused by lymphoma, metastatic tumors, to early surgical removal to confirm the diagnosis in order to early treatment is the best.
