Lymph node enlargement is very common and can occur in people of any age. It can be seen in a variety of diseases, both benign and malignant. Therefore, it is very important to pay attention to the causes of lymph node enlargement to avoid misdiagnosis or missed diagnosis. Let’s talk about the common causes of swollen lymph nodes. There are multiple enlarged lymph nodes of varying sizes on one or both sides of the neck, generally located at the anterior and posterior edges of the sternocleidomastoid muscle. In the early stages, the swollen lymph nodes are hard, painless, and can be moved. As the lesion continues to develop, lymphadenitis occurs, causing the lymph nodes to adhere to the skin and surrounding tissues. The lymph nodes may also adhere to each other and fuse into clumps, forming nodular masses that are difficult to move. In the late stage, the lymph nodes undergo caseous necrosis and liquefaction, forming cold abscesses. After the abscess ruptures, bean curd-like or rice soup-like pus flows out. Finally, a sinus tract or chronic ulcer that does not heal for a long time is formed, the skin at the edge of the ulcer is dark red and undercover, and the granulation tissue is pale and edematous. The above-mentioned lesions at different stages may appear simultaneously in various lymph nodes of the same patient. After the patient's disease resistance is enhanced and appropriate treatment is given, tuberculosis lesions in the lymph nodes can stop developing and calcify.

A small number of patients may have symptoms of systemic poisoning such as low fever, night sweats, loss of appetite, and weight loss. A clear diagnosis can usually be made based on local signs of tuberculosis exposure history, especially when cold abscesses have formed, or sinus tracts or ulcers have ruptured to form long-lasting sinuses. If necessary, a chest X-ray can be performed to determine whether there is tuberculosis. For pediatric patients, the tuberculin test can aid in the diagnosis. For example, there is only cervical lymph node enlargement, but no cold abscess or ulcer formation. Swollen lymph nodes should be treated promptly, and applying Chinese medicine Wanjin ointment externally can have a healing effect.
