The supraclavicular lymph nodes belong to the subgroup of deep lateral cervical lymph nodes, located near the subclavian artery and brachial plexus. Malignant tumors of multiple organs throughout the body can metastasize to the supraclavicular lymph nodes through the lymphatic route, and metastasis to the left supraclavicular lymph nodes is especially common.
Supraclavicular lymph node enlargement is often analyzed from the following aspects:
1. Acute infection: diseases caused by bacteria and viruses, such as upper respiratory tract infection and acute cellulitis.
2. Chronic infections
3. Tuberculous lymph nodes and non-tuberculous lymph nodes are the main causes of enlarged lymph nodes in people’s necks, and the common site of onset is the cervical lymph nodes. The clinical symptoms of tuberculous enlarged lymph nodes include low fever, fatigue, night sweats and other symptoms of tuberculosis intoxication, and tenderness on physical examination. 4. Metastasis of malignant tumor body surface lymph nodes: for example, gastric cancer and lung cancer are prone to swelling of supraclavicular lymph nodes. The clinical manifestations of metastatic enlarged lymph nodes are mainly painless progressive enlargement, hard to palpation and poor mobility.
