Which description best represents the normal border of a skin spot?

• A. irregular, scalloped or fuzzy edges
• B. regular, smooth, distinct
• C. jagged and uneven
• D. blurred

Answer: (B)

Normal borders of a benign skin spot are regular, smooth, and clearly defined. This tidy, even edge reflects uniform growth and a contained lesion with a symmetrical outline. In contrast, borders that are irregular, scalloped or fuzzy suggest uneven growth and potential concern, since malignant or pre-cancerous changes often alter margins. Jagged or uneven edges and blurred borders similarly raise concern for abnormal changes or spread. So, describing a lesion as regular, smooth, and distinct best matches what a normal border looks like.
