A firm, irregularly-shaped, pink-colored nodule or persistent red lesion is characteristic of squamous cell carcinoma. A pearly papule with prominent blood vessels is a characteristic of a basal cell carcinoma. A tender, rough, scaly, sandpaper-like patch is a characteristic of actinic keratoses (a precancerous lesion).
