Actinic keratosis - Symptom

Alternative Names

Solar keratosis; Sun-induced skin changes - keratosis; Keratosis - actinic (solar)

Symptoms:

  • Rough and dry skin lesion
  • Patch or growth on the skin
    • Limited to one area (localized)
    • Located on the face, scalp, back of the hands, chest, or other sun-exposed areas
    • Gray, pink, red (erythematous), or the same color as the skin
    • Begins as flat and scaly areas
    • Later develops a hard and wart-like or gritty, rough, and "sandpapery" surface -- may develop a horn-like texture

The skin lesion may be easier to feel than to see.

Signs and tests:

The health care provider makes the diagnosis based on the appearance of the skin growth. A skin biopsy may reveal any cancerous changes, if they occur.
