Abstract
The healing of minimal skin lesions is usually obtained by epidermal migration and proliferation from peripheral wound margins. However, cutaneous grafts or reconstituted skin are necessary for severe injuries. Various models have recently been reproduced for this purpose. The aim of this work is to report the histopathologic evolution of burn lesions treated two years ago by autologous epidermis (Genzyme Tissue Repair, Boston, USA). Fifteen patients with severe burns (more than 80% of surface) have been treated. These observations have been based exclusively on biopsies of grafted wounds. Cultured epidermis is rapidly fully differentiated after grafting with temporary hyperplasia and normal strata. At 18 months, rete ridges formation is present only in young patients. Melanocytes and Langerhans' cells repopulated grafts rapidly. The use of cultured epidermis nowadays represents an important improvement in burn treatment.
