The following statement about Keloid is true:
The following statement about Keloid is true:
Show Hint
Keloids overflow past the wound and recur after excision - their engine is excess growth factor.
Updated On: Jun 23, 2026
- It contains growth factor
- Extended excision is the treatment of choice
- It does not extend beyond the wound
- None of the above
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Frame the question by contrasting keloid with hypertrophic scar. The pathology of a keloid is overactive fibroblasts and a surplus of cytokines and growth factors such as $TGF\beta$, which keep collagen production switched on.
Step 2: Because of that growth-factor excess, statement (a) is correct: keloids do contain growth factor. This is the biochemical signature that explains their relentless growth.
Step 3: Knock out the wrong options. Spreading past the wound edge is the textbook way to tell a keloid from a hypertrophic scar, so (c) is false. Cutting it out widely tends to trigger recurrence, frequently larger, which is why plain extended excision is not the treatment of choice, making (b) false.
Step 4: With at least one true statement present, None of the above (d) is ruled out. The valid statement is that a keloid contains growth factor.
\[\boxed{\text{It contains growth factor}}\]
