Experimental analysis of a keloid on upper arm by using biomechanical devices

International audience Keloid scars are benign skin tumors-like, that affect only humanity, and more specifically asian and african populations. Keloids consist in the excessive accumulation of dermal collagen that extends beyond the boundaries of the original wound [1]. They are located on specific sites, tend to enlarge over time, and pose cosmetic and psychological problems for patients. The physiopathology of keloids is unclear and there is still no therapeutic consensus. Nevertheless it appears that keloids result from a combination of genetic, cellular and mechanical factors [2].The present study deals with a multi-devices experimental analysis in order to characterize the mechanical behavior of the keloid, the surrounding healthy skin and the contralateral healthy skin on the left upper arm of one young female clinical case.
