From ancient Egypt to the dermatologic office: An overview of skin substitutes and modern-day applications in dermatologic surgery.

Skin grafting (specifically xenografting) dates back to as early as 1500 before Christ (BC) in the Ebers papyrus, an Egyptian medical papyrus. In 1503, the use of human skin allograft was described in the manuscript of Branca of Sicily, and among the Hindu Tilemaker Caste approximately 2500-3000 years ago, surgeons repaired defects secondary to nose amputations of those who committed adultery and thievery. Over the years, many advancements in skin grafts/substitutes and their applications have propelled the field to focus on better graft survival, contracture prevention, cosmesis, and quality of life. We provide a general overview of skin substitutes (SS) with a particular focus on placental SS and their current applications in dermatologic surgery.
