People of Asian descent are among the groups more likely to develop keloid scars. People who have ancestry from Sub-Saharan Africa, Asia, or Latin America are more likely to develop a keloid. Among ethnic Chinese in Asia, the keloid is the most common skin condition. In the United States, keloids are more common in African Americans and ...
Dr. Turegano says keloids can form after an injury, but they can also occur in a surgical scar, ear piercing, tattoo, or in skin conditions like acne or chicken pox.
Prolonged cases of AKN can cause keloid formation due to chronic irritation from folliculitis. Bacterial folliculitis and acne can mimic the appearance of AKN; however, unlike acne, comedones are not seen with AKN. Treatments for AKN aim to reduce inflammation and prevent infections and scarring.
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 ...
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.
Clarification please: A sentence in the current revision is "It is speculated that people who possess any degree of African descent, regardless of skin color, may be especially susceptible to keloid occurrences." According to Mitochondrial Eve, a common ancestor of all humans comes from Eastern Sub-Saharan Africa. As such, all humans are of ...
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]
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
