• Are usually painless, but may become irritated and itch
• Are yellow, brown, black, or other colors
• Have a slightly raised, flat surface
• May have a rough or wart-like texture
• Often have a waxy surface
• Have a round-to-oval shape
• May have a "pasted-on" appearance
• May be single, but are usually many growths
