Keloids/Hypertrophic Scars
Keloids are the result of an overgrowth of dense fibrous tissue that usually develops after healing of a skin injury. The tissue extends beyond the borders of the original wound, does not regress on its own, and recurs after excision. It may occur after any major operation like Bypass surgery for Heart or if an individual has a keloidal tendency.
Keloids may form on any part of the body like the upper chest, shoulders and upper back are especially prone to Keloid formation. Symptoms include pigmentation of the skin, itchiness, redness, unusual sensations and pain.
Keloids can occur in about 10% of people. Both genders are equally affected.
A hypertrophic scar looks similar to a Keloid. Hypertrophic scars are more common. They don’t get a big as Keloids, and may fade with time. Keloids are considered a benign tumor, but they are mainly a cosmetic nuisance and never become malignant.
Treatments :
- Intralesional steroid injections
