#Keloid is often an active biological process. Over time, #keloids grow and become larger, and even merge with the nearby keloids. This aspect of keloid biology has not been adequately studied. Clearly, from observation alone, we can conclude that certain growth activating pathways remain active over time and result in progression and enlargement of keloids. Formation of keloids is often triggered by an injury to skin. Such an injury can clearly result in induction of pathological pathways that ultimately form #keloidTissue. These pathways are either shut down at some point in future, resulting in a growth arrest of the keloid, or the pathways remain autonomously active and are not shut down, thereby causing growth and progression of keloid. The two images below clearly show progression of the chest #keloids in this particular patient. The images were taken are approximately one year apart. ow.ly/Hvm1m
