Stretch marks and scars
How is it diagnosed?
The diagnosis of scars is clinical. Normotrophic scars are flat and well distended, non-rigid and undetected on the surface. The forming skin is soft and liftable in folds. Atrophic scars are slightly indented due to a lack of collagen that fails to completely fill the damaged area, and are especially common after acne or chicken pox. Hypertrophic scars are raised due to excessive collagen production. Keloids are characterized by overproduction of connective tissue, and become larger than the original lesion.
The diagnosis of stretch marks is clinical. Initially, stretch marks are purplish-red in color, due to the thinness of the epidermis, which highlights the underlying venous network. Later, the stretch marks "heal", and assume a pearly white color and appear slightly hollow.
How is it treated?
Scars and stretch marks can be treated with microablative laser, or by surgical removal in case of very large keloids. It is possible to use topical corticosteroids for keloids.
