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.
