A keloid scar has extended beyond the original wound margin. The patient requests treatment. Which of the following describes a keloid scar as distinct from a hypertrophic scar?
- A Keloid remains within the wound boundaries; hypertrophic extends beyond
- B Keloid extends beyond the original wound boundaries; hypertrophic remains within and regresses with time ✓
- C Keloid is more common on the limbs; hypertrophic on the face
- D Both keloid and hypertrophic scars regress within 2 years
Correct answer: B. Keloid extends beyond the original wound boundaries; hypertrophic remains within and regresses with time
Explanation
The cardinal distinguishing feature: keloid scars invade beyond the original wound margins and do not regress spontaneously, whereas hypertrophic scars are confined to the wound boundaries and often regress over 12–24 months. Keloids are more common in dark-skinned individuals, are prone to recurrence after excision, and are best treated with combined modalities (excision + intralesional steroids or post-excision radiotherapy).
