What are keloids or hypertrophic scars?
A keloid or hypertrophic scar is a type of raised scar. When skin is injured, wound healing process starts to repair and heal it. Sometimes this healing tissue grows excessively forming raised scars like hypertrophic scars or keloids. Hypertrophic scars are confined within margins of wound but keloids can be larger than the original wound.Keloids can develop in any part of the body however are more commonly found on chest (pre sternal area), ears, neck, shoulders and back.
Why are keloids or hypertrophic scars formed?
Keloids are formed when the healing process that place after injury, gets overactive. Keloids and hypertrophic scars represent an excessive tissue response to dermal injury characterized by local fibroblast proliferation and overproduction of collagen.Dark skinned individuals are more prone to keloid formation. Following types of injuries can contribute to formation of keloids:
- Surgical incision sites
- Acne scars
- Chicken-pox scars
- Ear piercing
- Vaccination sites
What are the symptoms of hypertrophic scars or keloids ?
They are skin colored to hyperpigmented or erythematous raised nodular scars. Most of smaller lesions are asymptomatic while larger lesions can have itching or pain. There is strong tendency of recurrence.
What is the difference between a keloid and a hypertrophic scar?
Hypertrophic scars are smooth surfaced raised plaques and confined to margins of original wound. Keloids can extend beyond the margins of original wound and at periphery it can have claws like appearance.
How does doctor diagnose keloid or hypertrophic scar?
Clinically. Generally no test required. Rarely skin biopsy can be done to differentiate from other cuase of firm nodules.
How are keloids or hypertrophic scars treated?
Keloids can be difficult to get rid of, and some return after treatment. Following are the treatment options:
Silicon or onion extract creams: They can be used for smaller new lesions to prevent further growth. They are minimally effective in old matured lesions.
Silicon get sheets: Sometimes these gel sheets are beneficial in reducing size and thickness of lesion. They need to apply for certain hours in a day for 3-4 months. They are useful in linear ans small lesions.
Intralesional injection: Keloids or hypertrophic scars are usually treated by intralesional steroid or 5FU injection. When injected into the keloid, these medicines help to shrink the scar. Usually, 3-4 treatments are required, 3-4 weeks apart.
Cryotherapy: Here, the lesionis frozen using a probe containing liquid nitrogen. It can be a bit painful. Following the treatment, a blister forms around the keloid and it falls of along with the dead tissue eventually in 1-2 weeks.
CO2 Laser Scar treatment:Raised scars can also be treated by Co2 laser treatment. This will reduce thickness of keloid or hypertrophic scar, making it less noticeable. CO2 laser treatment for raised scars can be combined with intralesional injections of steroid and 5 FU to get faster results and prevent recurrences.
Surgical excision:It is least preferred option specially for keloids because of high tendency of recurrence. Ear lobe keloids are generally treated by surgical excision. Surgery is followed by injections of steroids at edges of wound to prevent recurrence.
