Progressive enlargement of superficial lymph nodes

Introduction Superficial lymph nodes are distributed in groups, and each group of lymph nodes receives a certain part of lymph fluid. The lymph nodes in the ear and mastoid areas receive lymph fluid from the scalp; the submandibular lymph node group receives the lymph nodes at the base of the mouth, buccal mucosa, and gums; the axillary lymph nodes collect the lymph nodes, the lips and the tongue in the lower triangular region. liquid. Deep cervical lymph nodes collect lymph in the nasopharynx, larynx, trachea, thyroid, etc.; right supraclavicular lymph nodes receive lymphatic fluid in the trachea, pleura, lung, etc.; left supraclavicular lymph nodes receive lymph in the esophagus, gastrointestinal and other organs. The lymph node is enlarged 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. The progressive enlargement of superficial lymph nodes is one of the important positive signs of malignant lymphoma.

Cause

1EB virus infection;

2 immunodeficiency is a high-risk group;

3 ionizing radiation can also cause it to occur;

4 genetic factors have also been reported. Sometimes obvious family aggregation is visible.

Differential diagnosis

Clinically often differentiated from lymphadenitis. In people's lives, people often have a cold or other infection, neck, ear, armpit or groin can appear as a nodule of glass sphere size, local redness and tenderness, according to the hard, this is suffering from lymphadenitis. Lymphadenitis is often secondary to other purulent infectious diseases. The lymph nodes are swollen and tender. If the patient has strong resistance, there is no systemic symptoms and he can heal without treatment. Heavier local redness and heat pain, very accompanied by chills and fever, headache and other symptoms, through timely antibacterial anti-inflammatory treatment, redness can be resolved, but sometimes due to inflammation caused by tissue hyperplasia, can leave a small induration. If the inflammation is not controlled in time, it spreads to the lymph nodes and sticks to each other. In severe cases, an abscess can form.
