Keloid

Overview- About Keloid Problem And Treatment

A keloid scar is the result of a specific scar process in the dermis. While a scar remains relatively flat in normal time, the keloid scar develops in relief. At first, we notice the development of a small hard red-brown ball. This nodule develops, thickens and widens. The keloid scar can extend from a few millimeters to several centimeters.

It is said that a keloid scar is a fibroproliferative scar. It is caused by an abnormal proliferation of skin tissue. Some skin cells, fibroblasts, make too much collagen (a glycoprotein that is essential for skin regeneration and resistance). The accumulation of collagen is responsible for the thickening of the skin tissue and the development of the keloid scar.

Clinical observations suggest that keloid scars are more common in joint areas. The tension of the skin in these areas could favor the development of these scars. They are more often observed in the following regions:

1. The sternum area (bone located at the front of the chest at the midline of the body)
2. The deltoid region (at the level of the deltoid muscle constituting one of the muscles of the shoulder)
3. The upper area of the back ears
