Autografting of fat cells is widely used in plastic surgery in breast reconstruction, burn scars, unsightly scars etc. It is known that the autografting of fat cells not only makes it possible to bring adipocytes, and thus to create a volume, but also promotes neo-angiogenesis by providing the growth factors which allows an improvement of the local cutaneous tissue.

Currently the investigators perform this action in their service on healed eschars, by analogy with burn scars that are also dystrophic, so as to improve cutaneous trophicity, and reduce the recurrence of eschars on these scars. However, the literature on the autografting of fat cells on eschars is limited.
