|
| Symptoms: | - Rough and dry textured skin lesion
- A macule, patch, or growth on the skin
- Limited to a discrete area (localized)
- Located on the face, scalp, back of the hands, chest or other sun-exposed areas
- Color gray, pink, red (erythematous), or the same color as the skin
- Surface is initially flat and scaly, then becomes slightly raised
- Surface texture becomes hard and wart-like or gritty, rough, and "sandpapery"; may develop a horn-like texture from overgrowth of skin keratin layer (hyperkeratosis)
Note: The skin lesion may be easier to feel than to see.
