Which term best describes a flat, pigmented lesion?

• A. Macule
• B. Vesicle
• C. Papule
• D. Nodule

Answer: (A)

The main idea here is how skin lesions are described by color, elevation, and size. A flat, pigmented area means the skin surface is level (not raised) and shows a color difference from surrounding skin. That exact description fits a macule: a flat, non-palpable area that is pigmented and typically measures less than 1 cm in diameter. If such a pigmented area were larger than 1 cm, it would be called a patch instead. The other terms describe different features: a vesicle is a small, fluid-filled elevation; a papule is a small, raised solid bump; a nodule is a larger, raised solid mass. Since the lesion described is flat and pigmented, it aligns with macule as the best fit.
