The vascular lesions associated with skin necrosis in renal disease.
Three renal allograft recipients and one uraemic patient presented with skin necrosis. In all cases, the subcutaneous arteries and arterioles were narrowed or occluded by mural calcification with or without intimal fibrosis. A review of the literature shows that uraemic patients or allograft recipients with skin necrosis involving the trunk or thighs have a poor prognosis while recovery is common in patients with more peripheral lesions. The aetiology of the arterial lesions is unknown. Their relationship to renal disorders and/or hyperparathyroidism is uncertain and therapy remains unsatisfactory.
