Hypertrophic scar

Hypertrophic Scar

A Hypertrophic Scar is a type of scar that forms on the skin as a result of excessive collagen deposition during the wound healing process. Unlike some other scar types, a hypertrophic scar is elevated but does not extend beyond the original boundaries of the wound. Over time, these scars may stabilize or even regress spontaneously, but they often leave a permanent mark.

Hypertrophic scar on the skin

Characteristics

• Elevated: These scars are raised above the level of the surrounding skin.
• Confined to Wound Area: They do not grow beyond the original wound boundaries, distinguishing them from keloid scars.
• Color: They are often red or darker than the surrounding skin.

Formation

• Occurs during the wound healing process.
• Triggered by excessive collagen production by the body in response to injury.

Differentiation from Other Scar Types

• Keloid Scars: Unlike keloids, hypertrophic scars do not extend beyond the wound's original borders.
• Atrophic Scars: Atrophic scars are indentations in the skin, whereas hypertrophic scars are raised.

Risk Factors

• Genetic predisposition
• Location and nature of the wound
• Infection or other complications during the healing process

Management and Treatment

• Treatment options include silicone gel sheets, corticosteroid injections, laser therapy, and surgical removal.
• Early intervention can minimize the scar's development.

Implications and Concerns

• Aesthetic and psychological impact, particularly for scars in visible areas.
• Potential for restricted movement if located near a joint.
