Upper extremity allotransplantation (UEA) is the more common type of vascularized composite allotransplantation of which more than 80 patients have benefited worldwide. These allografts include - along with the skin - the nail unit, a specialized epithelial appendage which may be the target of graft rejection. We report an UEA recipient who developed, as an initial manifestation of graft rejection, onychomadesis, that is shedding of the nail plate starting from the proximal nail bed. On this occasion, we reviewed the nail changes we have observed in a series of eight patients with UEA who were grafted and followed in our hospital since 1998 (mean follow-up period of 9.75 years). We also reviewed the relevant literature reporting nail changes in UEA recipients. A brief discussion on the significance of these changes in the context of UEA is provided with emphasis on onychomadesis, a finding usually related to graft rejection in this specific setting.
