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.
It is a result of an overgrowth of granulation tissue (collagen type III) at the site of a healed skin injury which is then slowly replaced by collagen type I. Keloids are firm, rubbery lesions or shiny, fibrous nodules, and can vary from pink to the color of the person's skin or red to dark brown in color. A keloid scar is benign and not ...
“Tretinoin (topical retin-A) can help in early superficial scarring from acne and stretch marks, but [they are] not helpful for [raised scars like] hypertrophic scars and keloids,” says McMichael.
Hypertrophic scars are often distinguished from keloid scars by their lack of growth outside the original wound area, but this commonly taught distinction can lead to confusion. [6] Keloid scars can occur on anyone, but they are most common in dark-skinned people. [7] They can be caused by surgery, cuts, accident, acne or, sometimes, body ...
The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. [1] The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [3]
For the Nuba tribe of Sudan, scars can serve a medicinal purpose; scars above the eyes are believed to improve eyesight, and scars on the temples are believed to help relieve headaches. [14] In some cultures, scarification is used in traditional medicine to treat some illness by inserting medicine (usually herbs or powdered root) under the skin ...
Hypertrophic scar. Silicone gel sheeting is the gold-standard and non-invasive treatment for hypertrophic and keloid scars. During skin injury repair, dermal cells proliferate and migrate from the skin tissue to the wound, producing collagen and causing contraction of the placement dermis. [5]
Because of the differences between mucous membranes and the skin (e.g., keratinizing mucosa does not have a stratum lucidum and non keratinizing mucosa does not have this layer or normally a stratum corneum or a stratum granulosum), sometimes specialized texts give slightly different definitions of hyperkeratosis in the context of mucosae.
