Cryopreserved, cultured, allogenic, human epidermal grafts for the treatment of chronic ischemic ulcers: A report on two cases

Abstract

Cultured, allogenic, human epidermal grafts have been successfully used to treat extensive burns, donor sites, leg ulcers, and eroded areas in recessive dystrophic epidermolysis bullosa. The following report describes the use of cryopreserved cultured human epidermal allografts in the treatment of long-standing ischemic ulcers unresponsive to conventional medical therapy in two patients who had previously undergone unsuccessful vascular reconstructive surgery. A marked reduction in ulcer size as well as rapid pain relief was achieved in both patients. In selected cases the use of epidermal grafts as a biologic topical therapy could represent an alternative to other medical treatments. However, thus far, only a few cases have been reported and the uncertain short- and long-term results as well as the excessive costs may limit the widespread application of this treatment modality.
