During healing of a surgical wound, overgrowth a collagenous or fibrous scar tissue at the site of the wound is known as?

Appeared in: PGIMS Rohtak NO - 2017

Explanation

A keloid is an abnormal proliferation of scar tissue that forms at the site of a skin injury.
It is characterized by the excessive deposition of collagen, causing the scar to grow beyond the original boundaries of the wound.
Keloids do not regress on their own and can be firm, smooth, and sometimes itchy or painful.
This phenomenon is more common in individuals with darker skin tones and has a genetic predisposition.

Option A: Granulation tissue is a normal and essential part of the wound healing process (proliferative phase), where new tissue and blood vessels fill the wound bed. It is not an overgrowth of scar tissue.
Option C: A haematoma is a collection of blood under the skin or in an organ, resulting from a broken blood vessel. It is a complication of trauma or surgery but is not composed of fibrous scar tissue.
Option D: Exudate is fluid, such as pus or clear fluid, that leaks out of blood vessels into nearby tissues. It is a component of the inflammatory response, not a type of solid scar tissue.

Clinical Relevance

Nursing practice connection: Knowing Abnormal Wound Healing and Scar Formation helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Nurses play a key role in assessing wounds and identifying complications like keloids. Early identification allows for timely intervention to manage symptoms and appearance.
Management options for keloids include silicone gel sheets, pressure therapy, intralesional corticosteroid injections, cryotherapy, and laser treatment. Surgical excision alone has a high recurrence rate.
Patient education is crucial. Nurses should advise patients with a predisposition to keloids to avoid elective cosmetic procedures or piercings, especially in high-risk areas like earlobes and the chest.

How to Approach the Question

First, identify the key terms in the question: "overgrowth," "collagenous or fibrous scar tissue," and "at the site of the wound."
The term "overgrowth" is a critical clue, suggesting an abnormal or excessive healing process.
Next, evaluate each option based on its definition in the context of wound healing.
Recall the definitions: Granulation is new tissue, Haematoma is a blood collection, and Exudate is fluid.
Recognize that "Keloid" is the specific term for an overgrowth of scar tissue that extends beyond the wound's original margins.
Therefore, match the description in the question to the definition of a keloid to find the correct answer.
