What type of scar results from excessive hair growth following trauma?

Keloid scars are a type of raised scar that occurs when the body’s healing process goes into overdrive after an injury or trauma. These scars are characterized by the abnormal growth of fibrous tissue and can extend beyond the original wound site. In some cases, keloids may develop in areas where there is excessive hair growth due to trauma, which can further stimulate the growth of fibroblasts, the cells responsible for collagen production.

Patients with a genetic predisposition to keloid formation may find these scars to be particularly prominent. Unlike hypertrophic scars, which remain within the boundaries of the original wound, keloids can continue to grow and can be larger than the injury itself. They may also be itchy or painful and can affect the appearance and movement depending on their size and location.

The other types of scars mentioned do not fit this specific scenario: hypertrophic scars are raised but stay confined to the original injury area; atrophic scars are flat and often a result of conditions like acne; and contracture scars occur when skin or underlying tissues tighten, often as a result of burns. Understanding the behavior and characteristics of keloid scars helps in identifying the proper treatment options, such as corticosteroid injections or surgical removal, if necessary
