Which term describes a solid, round or oval elevated lesion greater than 1 cm in diameter?

• A. Nodule
• B. Wheal
• C. Ulcer
• D. Macule

Answer: (A)

A nodule is defined as a solid, round or oval elevated lesion that measures greater than 1 centimeter in diameter. This term is often used in dermatology and pathology to describe a type of skin lesion that can vary in depth but is typically characterized by its firmness and distinct boundary. Nodules can arise from various conditions, including infections, inflammatory processes, or neoplastic growths. In contrast, wheals are typically transient, raised areas that result from localized edema and are often associated with allergic reactions. Ulcers refer to open sores or lesions that extend into the deeper layers of the skin, and macules are flat lesions that are less than 1 centimeter in diameter. These distinctions highlight why nodule is the accurate answer in this context, focusing specifically on the characteristics of size and elevation that define it.
