Keloid it may ulcerate. Removing the scar is one treatment option; however, it may result in more severe consequences: the probability that the resulting surgery scar will also become a keloid is high, usually greater than 50%. Laser treatment has also been used with varying degrees of success. Keloids form within scar tissue. Collagen, used in wound repair, tends to overgrow in this area, sometimes producing a lump many times larger than that of the original scar. They can also range in color from pink to red. Although they usually occur at the site of an injury, keloids can also arise
Vascular endothelial growth factor A syndrome, also known as Crow-Fukase syndrome. Mutations in this gene have been associated with proliferative and nonproliferative diabetic retinopathy. In ischemic cardiomyopathy, blood flow to the muscle cells of the heart is either partially or completely reduced, leading to cell death and scar tissue formation. Because the muscle cells are replaced with fibrous tissue, the heart loses its ability to contract, compromising heart function. Normally, if blood flow to the heart is compromised, over time, new blood vessels will develop, providing alternative circulation to the affected cells. The viability of the heart following severely restricted blood flow is dependent on
