Nodular type: tuberculosis such as beans, one or more gradually leaping, skin color unchanged, solid, no pain, no fever. Infiltrative type: the tuberculosis does not heal after treatment, the nucleus may grow progressively, conscious pain, obvious perilymphadenitis occurs, accompanied by pressure pain, limited mobility, caseous necrosis can be seen in the nucleus. Abscess type: pain aggravation, fluctuating sensation when pressed, abscess formation. Ulcer type: the abscess breaks, pus clear more folder with septic floss-like material, sores in the carrion color gray, into the late stage. Often the sores do not converge for a long time, the pus drips continuously, the formation of fistula, or here and there ulcer, or even extended to other places.
