Seborrheic keratoses are benign tumors, beige to brown in color, 3–20 mm in diameter, with a velvety or warty surface. They appear to be stuck or pasted onto the skin. They are extremely common especially in the elderly and may be mistaken for melanomas or other types of cutaneous neoplasms. Although they may be frozen with liquid nitrogen or curetted if they itch or are inflamed, no treatment is needed.
