Pathology · Wound healing: keloid
Sample itemWhat distinguishes a keloid from a hypertrophic scar?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Keloid extends beyond the original wound boundaries
Keloids are excessive scars that grow beyond the original wound edges and may persist or recur after excision. Hypertrophic scars remain confined to the wound boundary and often regress over time.
Option by option
A. Keloid extends beyond the original wound boundaries (correct)
Correct. Extension beyond the original injury defines keloid.
B. Keloid always regresses rapidly
Keloids tend to persist rather than rapidly regress.
C. Hypertrophic scars never contain collagen
Hypertrophic scars contain abundant collagen.
D. Keloid occurs only after burns
Keloids can follow many skin injuries, not only burns.
