Papules are solid elevations that measure less than 0.5 cm in diameter. A common cause is allergic eczema. Which statement best defines papules?

• A. Solid elevations that are less than 0.5 cm in diameter
• B. Fluid-filled blisters larger than 1 cm
• C. Flat patches of skin
• D. Pus-filled nodules

Answer: (A)

Papules are small, raised, solid spots on the skin that do not contain fluid. The key idea is that they are solid rather than fluid-filled and are small in size, typically described as under half a centimeter in diameter. This makes the statement “solid elevations that are less than 0.5 cm in diameter” the best fit. In eczema or allergic dermatitis, such papules arise from the inflammatory response as skin becomes irritated and itchy. By contrast, fluid-filled lesions like vesicles or blisters contain fluid (and a blister is usually larger, often over 1 cm, which would not be a papule). Flat patches describe non-raised areas of skin, and pus-filled lesions are pustules or abscesses, not solid raised lesions.
