Complications

By Mayo Clinic staff

Impetigo typically isn't dangerous, but complications can sometimes occur. Examples include:

  • Scarring. The ulcers associated with ecthyma, a deeper and more serious form of impetigo, can leave scars.
  • Cellulitis. This potentially serious infection affects the tissues underlying your skin and eventually may spread to your lymph nodes and into the bloodstream. Left untreated, cellulitis can quickly become life-threatening.
  • Kidney problems. One of the types of bacteria that cause impetigo can also damage your kidneys.
