cervical lymph node tuberculosis
Introduction
Introduction to cervical lymph node tuberculosis Chinese medicine for cervical lymph node tuberculosis is called and is more common in children and young people. Most of the tubercle bacilli are invaded by tonsils and caries, and a few tuberculosis lesions secondary to the lungs or bronchi. However, it can only cause disease when the body's disease resistance is low. The disease period is usually 1 to 3 months or longer. Multiple lymph nodes are swollen and scattered, which can be promoted. With the development of the disease, it can be fused into clumps, fixed, unable to push, and finally the cheese-like necrosis forms a cold abscess, which forms a chronic sinus after rupture. Chest X-rays may show tuberculosis. basic knowledge The proportion of illness: 0.005% Susceptible people: no specific people Mode of infection: respiratory infection Complications: tuberculous mesenteric lymphadenitis tuberculosis children with acute hematogenous disseminated tuberculosis
Cause
Cervical lymph node tuberculosis
Causes
Tuberculosis infection
Lymph node tuberculosis is the primary tumor caused by tuberculosis through the upper respiratory tract or with food in the mouth and nasopharynx, especially the tonsil gland. After infection, it reaches the neck along the lymphatic vessels. The deep lymph nodes are mostly unilateral. Lymph node involvement, after absorption of the pharyngeal disease, the affected lymphatic tuberculosis continues to develop, forming a cold abscess or ulcer, followed by the tuberculosis of the blood tuberculosis after the primary tuberculosis infection with the blood into the medial cervical lymph node caused by cervical lymphatic tuberculosis, can also be from the waist Abdominal lymphatic infection, and then deep lymph nodes, secondary infections are more common in the pathogenesis of cervical lymph node tuberculosis, suffering from cervical lymph node tuberculosis.
Secondary factors of tuberculosis
Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis that can invade many organs and is most common in tuberculosis of the lungs. The bacteria are important sources of infection. Human infection with tuberculosis does not necessarily occur, and when the resistance is reduced or the cell-mediated allergic reaction is increased, it may cause clinical disease. If diagnosed in time and treated reasonably, most of them will be cured.
Prevention
Cervical lymph node tuberculosis prevention
1. Children should be vaccinated on time to avoid contact with tuberculosis patients.
2, children pay attention to nutrition, increase the intake of protein, vitamins, to avoid strenuous exercise.
3, cervical lymph node tuberculosis after treatment, most of the prognosis is good.
4, neck mass is more common in the clinical, early diagnosis, early diagnosis and treatment, control of the disease, so as not to affect the growth and development of children.
Complication
Cervical lymph node tuberculosis complications Complications Tuberculous mesenteric lymphadenitis, pulmonary tuberculosis, acute hematogenous disseminated pulmonary tuberculosis
Children with tuberculosis have a rapid onset and rapid progress, and children with limited endurance are prone to complications. If left untreated, they can be delayed in the short-term to all organs of the body (such as lungs, bones, brain, etc.).
Symptom
Cervical lymph node tuberculosis symptoms Common symptoms Lymph node enlargement Lymph node tuberculosis nails flattened chronic ulcer neck tumor abscess low heat night sweats thin loss of appetite
More on the side of the neck or on both sides of the sputum, gradually grow up, no pain, no itching, push and slide, no obvious tenderness, such as low body resistance, gradually increase, the skin becomes purple, and finally collapse, Flowing water like pus and discharging yellow turbid cheese-like things, and Chinese medicine called "mouse sores" repeated ulceration, a small number of patients may have low fever, night sweats, loss of appetite, weight loss and other systemic symptoms.
Examine
Examination of cervical lymph node tuberculosis
1. Chest X-ray or CT scan to determine whether there is damage to the lung structure.
2. Indirect laryngoscopy and posterior nasal examination can sometimes find tuberculosis, laryngeal tuberculosis and nasopharyngeal tuberculosis.
3. Tuberculin, PPD (purified protein derivative) test, erythrocyte sedimentation test is helpful for diagnosis. The tuberculin test (also known as the Muntu test, PPD test) is a tool for diagnosing tuberculosis. It is one of the two major tuberculin skin tests in the world and has largely replaced a variety of puncture tests, such as the Tine test.
Diagnosis
Diagnosis and diagnosis of cervical lymph node tuberculosis
diagnosis
According to the local signs of tuberculosis exposure history, especially when a cold abscess has been formed, or a sinus or ulcer that has been formed for a long time has been broken, a clear diagnosis can be made. If necessary, chest fluoroscopy can be made to determine whether there is a lung structure. In pediatric patients, the tuberculin test can help diagnose, such as only cervical lymphadenopathy, and no cold abscess or ulceration.
There are a number of enlarged lymph nodes of different sizes on one side or both sides of the neck. They are usually located in the anterior and posterior margins of the sternocleidomastoid muscle. In the initial stage, the enlarged lymph nodes are hard, painless, and can be promoted. The lesions continue to develop. Peri-inflammation of the lymph nodes occurs, causing adhesion of lymph nodes to the skin and surrounding tissues; each lymph node can also adhere to each other and fuse into a mass to form a nodular mass that is difficult to push. In the advanced stage, caseous necrosis, liquefaction, and formation of a cold abscess occur in the lymph nodes. After the abscess ruptures, the bean dregs or the thin soup-like pus are discharged, and finally a long-term unhealed sinus or chronic ulcer is formed; the skin of the ulcer is dark red, sneak, the granulation tissue is pale, edema, and the above-mentioned different stages of the lesion can simultaneously In the lymph nodes of the same patient, the patient's disease resistance is enhanced and after appropriate treatment, the lymph node tuberculosis can stop developing and calcification.
Differential diagnosis
The disease should be differentiated from chronic lymphadenitis of the neck, primary and metastatic malignant tumors of the neck.
