A small, uneven pigmented spot on the skin's surface is most commonly known as which lesion?

• A. Papule
• B. Mole
• C. Verruca
• D. Wheal

Answer: (B)

A small pigmented spot on the skin’s surface is most consistent with a mole. A mole, or nevus, is a benign pigmented lesion formed by melanocytes in the epidermis (and sometimes the dermis). It can be flat or slightly raised, and its color can be varied or uneven, which matches the description of a small, uneven pigmented spot.

The other terms describe different skin findings. A papule is a small raised bump that may or may not be pigmented, but its defining feature is elevation. A verruca is a wart, usually with a rough, grainy surface and sometimes irregular texture rather than just a pigmented spot. A wheal is a temporary, itchy swelling often seen in hives, and it’s not described as pigmented.
