Type
Skin Cancer
These lesions are composed of keratin (the protein found in fingernails) and feel hard to the touch. They often arise from an actinic keratosis (precancer) or an underlying squamous cell carcinoma. They vary in size and can be as small as the tip of a pencil lead. They generally develop on sun-damaged skin.
