Are there any malignant lymph nodes under the chin?

Lymph nodes are a relatively common tissue in the human body, and their distribution range is relatively wide. Different lymph nodes are located in different locations and have different functions, including the submental lymph nodes. Most lymph nodes are divided into benign and malignant, but some lymph nodes are not malignant. So, are there any malignant submental lymph nodes?

The phenomenon of lymph nodes increasing in size due to internal cell proliferation or tumor cell infiltration. Common clinical signs. It can be found by touching the submandibular, neck, supraclavicular fossa, axilla and groin areas, but enlarged lymph nodes in the body such as the hilum of the lung, mediastinum, retroperitoneum and mesentery can only be found by X-ray, CT and B-ultrasound. There are three common situations in which lymph nodes are swollen:

① Benign swelling. Includes swelling caused by various infections, connective tissue diseases and allergic reactions. The clinical course is usually benign and can be fully recovered within a certain period of time as the cause is eliminated.

② Malignant swelling. It includes malignant tumors originating in the lymph nodes, such as lymphoma, lymphocytic leukemia and malignant histiocytosis, as well as lymph node metastasis of other malignant tumors, such as lung cancer, gastric cancer and breast cancer. The clinical course is malignant, with persistent and progressive enlargement of lymph nodes. If not treated actively, the disease will often progressively worsen and lead to death.

③Swelling between benign and malignant. Such as angioprimitive immunocytic lymphadenopathy and angiofollicular lymphadenopathy. It often starts out benign but can become malignant and fatal. Therefore, after confirming that the lymph nodes are swollen, the key is to determine their cause and nature. Local swelling accompanied by obvious pain often indicates infection, while progressive painless swelling often indicates malignant tumor disease. Bone marrow aspiration and especially lymph node biopsy can help confirm the diagnosis. The treatment of swollen lymph nodes depends on the cause. For example, streptomycin and remifentanil can be used for lymph node tuberculosis. If it is malignant lymphoma, combined chemotherapy should be the main treatment. If it is late-stage cancer metastasis, the prognosis is extremely poor.
