If the body's resistance is low, it will gradually increase, and the skin will turn purple. Finally, watery pus will erupt and yellow turbid cheese-like pus will be discharged, which is called "rat sore" in Chinese medicine. Recurrent ulcers are rare, and some patients may have symptoms of systemic poisoning such as low fever, night sweats, loss of appetite and emaciation.
There are two causes of lymph node tuberculosis: one is the primary focus caused by Mycobacterium tuberculosis infecting the oral cavity and nasopharynx, especially the tonsil gland, through the upper respiratory tract or with food. Posterior lymphatic vessels reach superficial and deep lymph nodes in the neck. Most sites are unilateral lymph nodes. Affected pharynx. After absorption after severe illness, the affected lymph nodes continue to develop into cold abscess or ulcer.
The other is that after primary tuberculosis infection, mycobacterium tuberculosis in the blood enters the medial cervical lymph nodes with the blood, causing cervical lymph node tuberculosis; It can also spread from waist and abdomen lymph nodes to deep lymph nodes for secondary infection, which is more common in the pathogenesis of cervical lymph node tuberculosis.
