The cause of lymph nodes in children's neck

Children's immunity is relatively weak, so they must pay attention to protecting their bodies in daily life, and parents cannot take it lightly. Lymph is distributed in various parts of our body. If we do not pay attention to our body, it is likely to cause lymphatic diseases. Next, let’s talk about localized lymphadenopathy.

Common causes of localized lymphadenopathy include:

1. Infectious lymphadenopathy

It is seen in acute and chronic inflammation of tissues and organs within the drainage range of the lymph nodes, such as cervical lymph node enlargement caused by tonsillitis, gingivitis, etc.; axillary lymph node enlargement caused by inflammation of the chest wall, breast and other parts (picture); inguinal lymph node enlargement caused by infection of the perineum, buttocks, calves and other parts.

(1) Acute infection Lymph node enlargement caused by acute infection is characterized by soft texture, tenderness, smooth surface, and no adhesion. The swelling stops when it reaches a certain extent. They often shrink or disappear quickly after the application of effective antibacterial drugs.

(2) Chronic infection: The swollen lymph nodes caused by chronic infection are harder in texture, but they may eventually shrink or disappear.

(3) Gonorrhea Gonorrhea can cause tender inguinal lymphadenopathy on both sides.

(4) Chancroid Chancroid can cause unilateral tender lymphadenopathy;

(5) Syphilis Syphilis can cause unilateral or bilateral non-tender inguinal lymphadenopathy.

(6) Lymph node tuberculosis: Enlarged lymph nodes often occur around the blood vessels in the neck. They are multiple, of varying sizes, and slightly hard in texture. They may adhere to each other or to the surrounding tissues. If caseous necrosis occurs, fluctuation can be felt, and it may ulcerate in the late stage, forming a fistula that is difficult to heal and an irregular scar after healing.

2. Lymph node metastasis of malignant tumor

The swollen lymph nodes caused by tumor metastasis are hard in texture, sometimes feel rubbery, generally not tender, may be adhered to the surrounding tissues, and sometimes the boundaries of the swollen lymph nodes are unclear. If large, hard, non-tender lymph nodes appear in the left supraclavicular fossa, metastasis of gastric or esophageal cancer should be considered. This is the entrance where the thoracic duct enters the jugular vein. This enlarged lymph node is called Virchow's lymph node, which is a sign of metastasis of gastric cancer and esophageal cancer.

In fact, lymphadenitis often occurs around us. Generally, lymphadenitis does not cause particularly serious consequences, but this does not mean that we can ignore it. Children's immune systems are not fully developed, and even a minor illness may develop into an uncontrollable situation in their bodies, so we must always pay attention to children's health.
