Signs & Symptoms

Diagnosis & Treatment

General Measures:

  • If only a few actinic keratoses are present, cryotherapy (freezing with liquid nitrogen) is the most rapid and satisfactory treatment. If there are too many lesions to freeze, topical 5-fluorouracil (5-FU) applied to the affected area nightly or twice per day for 2 to 4 wk produces dramatic results.
  • Laser resurfacing is another therapeutic option.


Only topical medications listed above are necessary.
