Keloids
Keloids are a type of overgrowth that occurs in the skin. These abnormal, scar-like growths develop in response to injury and inflammation sites. They tend to occur at wound sites as well as along scars, such as those due to acne or surgery. Keloids can also develop on mucous membrane surfaces like the mouth and genitals. As they form around a wound site, keloid tissue may thicken and grow inward toward the deeper layers of skin or even down into muscle tissue. As they increase in size, they can cause pain and irritation by stretching the skin outwards.
