General reviews
Assumptions appearances keloids
Keloids are fibrotic tumors of the dermis that form during a protracted wound-healing process. The predisposition to form keloids is found predominantly in people of African, Asian, and Hispanic descent.

Although many hypothesis regarding the keloid formation have been speculated (alteration in genetic, immunologic, collagen turnover and growth factors) the pathology is still unknown and an efficient therapy is far from being established.
