Tuberculosis of lymph nodes is called "scrofula" in traditional Chinese medicine. Mycobacterium tuberculosis mostly invades from the oral cavity (dental caries) or tonsils, and no tuberculosis lesions are usually clinically visible at the site of invasion. A small number of tuberculosis lesions are secondary to the lungs or bronchi. The main clinical manifestation is cold abscesses in local lymph nodes, and systemic poisoning symptoms such as low fever, night sweats, and weight loss are less common. In the late stage, the lymph nodes become caseous, and the sinus tract does not heal for a long time after rupture, and there is a thin pus discharge resembling bean curd residue. Comprehensive treatment measures must be taken for this disease. While standardizing anti-tuberculosis treatment, proper removal of infected lymph nodes or scraping of sinus tracts can promote recovery.
