Lymph node tuberculosis is most often seen in adolescent children with or without pulmonary tuberculosis. In the initial stage, the enlarged lymph nodes are as big as a finger, only one or several of different sizes, with unchanged skin color, firm when pressed, movable when pushed and touched, not hot and not painful. In the middle stage, the swollen lymph nodes increase in size, the skin adheres to each other and fuses into a lump, which is not moving when pushed and touched, and the pain is gradually felt; if the skin color gradually turns dark red and there is a slight fluctuating feeling when pressed, then the internal pus has been established. At the later stage, the lump breaks down, the pus is clear and thin, with caseous necrosis, the sore is submerged (hollow shell), surrounded by purple and dark, the disease often heals and collapses, and can form sinus tracts or fistulas. Lymphatic tuberculosis is not terrible, as long as early, regular, appropriate, full and combined use of anti-tuberculosis drugs, and surgical removal of the lesion, the cure rate is as high as 98%.
