What Can Cause a Swollen Jaw?

When inflammation occurs in the submandibular lymph nodes, the bacteria and its toxins swell due to the stimulation of bacteria and toxins, which can be clearly touched by hand, often accompanied by pain symptoms. The causes are many. When an infection occurs in a part of the body and the bacteria pass through the lymph nodes with the lymph fluid, it can cause the swelling and pain of the lymph node group accordingly. When the body suffers from a malignant tumor, it often metastasizes along the lymphatic vessels, and stays in the lymph nodes to divide and proliferate, causing the lymph nodes to swell.

Submandibular lymphadenopathy

When inflammation occurs in the submandibular lymph nodes, the bacteria and its toxins swell due to the stimulation of bacteria and toxins, which can be clearly touched by hand, often accompanied by pain symptoms. The causes are many. When an infection occurs in a part of the body and the bacteria pass through the lymph nodes with the lymph fluid, it can cause the swelling and pain of the lymph node group accordingly. When the body suffers from a malignant tumor, it often metastasizes along the lymphatic vessels, and stays in the lymph nodes to divide and proliferate, causing the lymph nodes to swell.

The main clinical manifestations are fullness of the submandibular area, enlarged lymph nodes and tenderness.

1, there may be respiratory infections, oral inflammation, bloated, skin lesions and other primary infections.

2, local lymphadenopathy, pain, or redness, a sense of fluctuation, often accompanied by fever, loss of appetite and so on.

3. Perform lymph node biopsy if necessary to exclude malignant tumor infiltration.

Common diseases of lymphadenopathy:

Chronic lymphadenitis

Most of them have obvious infections, and often have localized lymphadenopathy, pain and tenderness. Generally, the diameter does not exceed 2 to 3 cm, and it will shrink after anti-inflammatory treatment. Inguinal lymphadenopathy, especially flat lymph nodes that are long-standing and unchanged, is not significant. However, there is no obvious cause of swelling of the lymph nodes in the neck and supraclavicular region, which indicates systemic lymphoproliferative diseases, which should be paid attention to and further confirmed.

Tuberculous lymphadenitis

Fever, sweating, fatigue, and increased erythrocyte sedimentation are more common in young adults. Often accompanied by tuberculosis, the texture of lymph nodes is uneven, some are lighter (cheese-like), some are harder (fibrosis or calcification), and adhere to each other, and adhere to the skin, so poor mobility. These patients are positive for tuberculin tests and blood tuberculosis antibodies.

Malignant lymphoma

It can also be seen in any age group, and its lymphadenopathy is usually painless and progressive, ranging from soybeans to jujubes with medium hardness. It is generally non-adhesive to the skin, and does not fuse with each other in the early and middle stages, and can move. In the later stage, the lymph nodes can grow very large, or they can fuse into large pieces, with a diameter of more than 20cm, which invades the skin and will not heal after ulceration. In addition, it can invade the mediastinum, liver, spleen, and other organs, including the lungs, digestive tract, bones, skin, breast, and nervous system. Definitive diagnosis requires biopsy. Clinically, malignant lymphoma is often misdiagnosed. Superficial lymphadenopathy is the first manifestation, and 70% to 80% are diagnosed with lymphadenitis or lymph tuberculosis at the initial diagnosis, which delays treatment.

Giant lymph node hyperplasia

Is a rare misdiagnosis. Often manifested as unexplained lymphadenopathy, mainly invading the thorax, most of the mediastinum, but also invading the hilum and lung. Other affected areas are the neck, retroperitoneum, pelvic cavity, axilla, and soft tissue. Often misdiagnosed as thymoma, plasmacytoma, malignant lymphoma. Understanding the pathology and clinical manifestations of the disease is extremely important for early diagnosis.

Pseudolymphoma

Masses that often occur outside the lymph nodes, such as orbital, gastric pseudolymphomas, and lymphatic polyps of the digestive tract. Generally considered to be a reactive hyperplasia, caused by inflammation.

Lymph node metastases

Lymph nodes are often stiff and uneven in texture, and primary lesions can be found. Rarely systemic lymphadenopathy.

Acute leukemia and chronic lymphocytic leukemia

Lymphadenopathy is also common, especially acute lymphoblastic leukemia common in children, which is clinically acute, often accompanied by fever, bleeding, liver and spleen enlargement, sternal tenderness, etc. Hematology and bone marrow aspiration can confirm the diagnosis.

Sarcoidosis

Rarely in our country, often invading bilateral hilars, is radial, accompanied by long-term low fever. Lymph nodes can swell throughout the body, especially before and after the ear, under the jaw, and near the trachea. It is difficult to distinguish clinically from malignant lymphoma.

Infectious mononucleosis

More common with young men and women, caused by EB virus, but patients are generally in good condition, may have fever and generalized lymphadenopathy, and may also have mild spleen enlargement. Heteromorphic lymphocytes are present in the peripheral blood, and a positive heterophilic agglutination test can confirm the diagnosis.

Serum disease

A disease that occurs after the use of serum products (tetanus antitoxin, rabies vaccine, etc.) for patients. A few patients have lymphadenopathy as the first clinical symptom. However, the lymph nodes on the injection site and the pulley are mostly enlarged. It can be diagnosed based on injection history and fever, rash, and eosinophilia.

Lymph node enlargement is very common. The above 10 diseases listed above are hopeful for enlightenment and timely consultation, diagnosis and identification in order to obtain timely and effective treatment.

1. Develop good living habits.

2, maintain a good mood and stable mood Have a healthy diet and usually eat more fruits and vegetables to improve self-immunity.

3. People who work in heavy oil fume must try to protect themselves. For example, wear a mask and go out regularly to breathe some fresh air. At least once a year to do an inspection.

4. Keep away from smoke, alcohol, drugs, pesticides, noise, volatile and harmful gases, toxic and harmful heavy metals, etc.
