A hypertrophic scar is a cutaneous condition characterized by deposits of excessive amounts of collagen which gives rise to a raised scar, but not to the degree observed with keloids. [1] Like keloids, they form most often at the sites of pimples, body piercings, cuts and burns. They often contain nerves and blood vessels.
Most skin injury types can contribute to scarring. This includes burns, acne scars, chickenpox scars, ear piercing, scratches, surgical incisions, and vaccination sites. According to the US National Center for Biotechnology Information, keloid scarring is common in young people between the ages of 10 and 20. Studies have shown that those with ...
Scars form differently based on the location of the injury on the body and the age of the person who was injured. [citation needed] The worse the initial damage is, the worse the scar will generally be. [citation needed] Skin scars occur when the dermis (the deep, thick layer of skin) is damaged.
A callus (pl.: calluses) is an area of thickened and sometimes hardened skin that forms as a response to repeated friction, pressure, or other irritation. Since repeated contact is required, calluses are most often found on the feet and hands, but they may occur anywhere on the skin.
Fibrosis, also known as fibrotic scarring, is the development of fibrous connective tissue in response to an injury. Fibrosis can be a normal connective tissue deposition or excessive tissue deposition caused by a disease.
The temporary raised skin on the site of a properly delivered intradermal (ID) injection is also called a welt, with the ID injection process itself frequently referred to as simply "raising a wheal" in medical texts. [10] Welts: Welts occur as a result of blunt force being applied to the body with elongated objects without sharp edges.
Aplasia cutis congenita (cutis aplasia, congenital absence of skin, congenital scars) Arteriovenous fistula; Benign neonatal hemangiomatosis; Branchial cyst (branchial cleft cyst) Bronchogenic cyst; Capillary hemangioma (infantile hemangioma, nevus maternus, strawberry hemangioma, strawberry nevus) Cavernous venous malformation
This will result in a linear scar. If the repair is made along a natural skin fold or wrinkle line, the scar will be hardly visible. Larger defects may require repair with a skin graft, local skin flap, pedicled skin flap, or a microvascular free flap. Skin grafts and local skin flaps are by far more common than the other listed choices.
