Which type of skin lesion is raised and solid but smaller than a nodule?

• A. Macule
• B. Pustule
• C. Papule
• D. Blister

Answer: (C)

A papule is characterized as a raised, solid skin lesion that is distinctively smaller than a nodule. The elevation of a papule forms as a result of an increase in the thickness of the skin or due to the accumulation of cells, causing it to protrude from the surrounding skin. Papules can vary in size but are generally less than 1 centimeter in diameter. They may be indicative of various skin conditions, including acne, eczema, or warts.

In contrast, macules are flat, discolored areas of the skin that do not involve any elevation, making them fundamentally different from papules. Pustules are also raised lesions, but they contain pus, distinguishing them from papules that are solid rather than fluid-filled. Blisters, on the other hand, are fluid-filled lesions that can be either raised or flat, typically resulting from friction or irritation, which differentiates them from the solid nature of papules. Thus, a papule is the appropriate term for a raised, solid lesion that is smaller than a nodule.
