Which description best represents an abnormal border of a skin spot?

• A. irregular, scalloped or fuzzy edges
• B. smooth, distinct
• C. uniform
• D. regular

Answer: (A)

Border irregularity signals abnormal growth pattern in a skin lesion, which is a red flag for possible malignancy. Benign spots tend to have smooth, even borders that outline a uniform shape. When the border is irregular, scalloped, or fuzzy, the edges blend into surrounding skin and the contour is uneven, suggesting the lesion isn’t growing in a uniform way. This irregular border is a classic feature seen in melanoma and other dangerous lesions, especially when combined with color variation or changes in size. Therefore, irregular, scalloped, or fuzzy edges best describe an abnormal border.
