Lymphatic tuberculosis is due to the invasion of tuberculosis bacillus in the neck caused by the specific infection, which occurs in the neck, armpits, submandibular, inguinal, etc., the local nodes swollen and hard as a nucleus, cumulative strings can also be a single one, in severe cases, can be ulcerated and pus. Tuberculosis early and no obvious symptoms, after the development of the disease can have systemic symptoms such as fatigue, loss of appetite, emaciation, low-grade fever, etc., and the local symptoms of the diseased organs.

Tuberculosis of the cervical lymph nodes is known as scrofula in Chinese medicine and is most common in children and young people. Most of the tubercle bacilli invade through tonsils, dental caries, and a few secondary to tuberculosis of the lungs or bronchial tubes. The disease can only be caused when the body's resistance is low. The onset of lymphatic tuberculosis is also related to physical fitness. The onset of cervical lymphatic tuberculosis is often 1 to 3 months or longer. It is characterized by multiple enlarged, scattered, pushable lymph nodes. As the disease progresses, it may fuse into a mass, become fixed and unpromotable, and eventually become caseous necrosis, forming a cold abscess that breaks down and forms a chronic sinus tract. Chest radiographs may show tuberculous foci.
