Superficial lymphadenopathy

Lymph nodes increase 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. There are three common conditions for lymphadenopathy: ① benign enlargement Including swelling caused by various infections, connective tissue diseases and allergies. Clinically, it is a benign process. With the removal of the cause, it can be completely recovered within a certain period of time. ② Malignant swelling. Includes malignant tumors such as lymphoma, lymphocytic leukemia, and malignant histiocytosis, and lymph node metastases such as lung cancer, gastric cancer, and breast cancer. The clinical manifestations are malignant and the lymph nodes are persistently enlarged. If they are not actively treated, they will often progress to progressive death. ③ Swelling between benign and malignant. Such as vascular primitive immune cell lymphadenopathy and vascular follicular lymphadenopathy. It is often benign at first, and can become malignant and lethal. Therefore, after the determination of lymphadenopathy, the key is to determine the cause and nature. Local enlargement with obvious pain often indicates infection; progressive painless enlargement often indicates malignant tumor disease. Bone marrow aspiration, especially lymph node biopsy, can help confirm the diagnosis. The treatment of lymphadenopathy is based on the disease. For example, streptomycin and remifen can be used for lymphatic tuberculosis. If it is malignant lymphoma, it should be combined with chemotherapy. If it is advanced metastasis, the prognosis is very poor. Lymph node enlargement is very common and can occur in people of any age. It can be seen in a variety of diseases, benign and malignant. Therefore, it is very important to pay attention to the cause of lymph node enlargement and seek timely diagnosis to avoid misdiagnosis and missed diagnosis. Let's talk about common causes of lymphadenopathy.
