Question

the abcde rule for recognizing early signs of malignant melanoma refers to which of the following characteristics of the lesion?
multiple choice
asymmetry, brightness, color, diameter, and elevation
aspect, brightness, color, distance, and evolution
asymmetry, border irregularity, color, diameter, and evolution
aspect, border irregularity, color, distance, and elevation
area, border irregularity, color, density, and elevation

Explanation:

The ABCDE rule is a mnemonic for recognizing melanoma. A stands for Asymmetry (one half does not match the other), B for Border irregularity (blurred or ragged edges), C for Color (variegated, e.g., shades of tan, brown, black, red, white, blue), D for Diameter (usually >6mm, though this is not absolute), and E for Evolution (changes over time in size, shape, color, elevation, or new symptoms like bleeding, itching). Analyzing each option:

• First option: "Brightness" is incorrect. The rule uses Border irregularity, not brightness.
• Second option: "Aspect" and "Brightness" and "Distance" are wrong. The correct terms are Asymmetry, Border irregularity, and Evolution (not distance).
• Third option: Matches Asymmetry (A), Border irregularity (B), Color (C), Diameter (D), Evolution (E).
• Fourth option: "Aspect" and "Distance" are incorrect. Asymmetry (not aspect) and Evolution (not distance) are part of the rule.
• Fifth option: "Area" and "Density" are wrong. Asymmetry (not area) and Border irregularity (already in the option but other terms are incorrect).

Answer:

Asymmetry, border irregularity, color, diameter, and evolution
