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.
Fibrosis, also known as fibrotic scarring, is a pathological wound healing in which connective tissue replaces normal parenchymal tissue to the extent that it goes unchecked, leading to considerable tissue remodelling and the formation of permanent scar tissue.
A keloid scar is benign and not contagious, but sometimes accompanied by severe itchiness, pain, [2] and changes in texture. In severe cases, it can affect movement of skin. In the United States, keloid scars are seen 15 times more frequently in people of sub-Saharan African descent than in people of European descent. [3]
Hypertrophic scars appear raised and thickened on the skin. They usually occur when the body produces too much collagen at the site of the wound during the healing process, according to Farber ...
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.
The ways to manage pain can be to modify pain management techniques used in the normal population. Pain is classified into several types. One is nociceptive, which is caused by an injury sustained to tissues. Another is neuropathic pain, caused by abnormal signals by the nervous system. In many cases, the pain individuals experience is an ...
Severe cutaneous adverse reactions (SCARs) are a group of potentially lethal adverse drug reactions that involve the skin and mucous membranes of various body openings such as the eyes, ears, and inside the nose, mouth, and lips. In more severe cases, SCARs also involves serious damage to internal organs. SCARs includes five syndromes:
The repaired region contains an abnormally large number of collagenous fibers, and relatively few blood vessels. Damaged sweat and sebaceous glands, hair follicles, muscle cells, and nerves are seldom repaired. They are usually replaced by the fibrous tissue. The result is the formation of an inflexible, fibrous scar tissue.
