title: Cutaneous gangrene due to hyperparathyroidism secondary to chronic renal failure (uraemic gangrene syndrome)
abstract: Cutaneous and subcutaneous gangrene are serious sequelae of secondary or tertiary hyperparathyroidism which may accompany chronic renal failure. Based on analysis of the present typical case and a retrospective survey of similar cases in the literature, we propose the term 'uraemic gangrene syndrome' for this association. These skin lesions in chronic renal failure patients represent the most serious clinical manifestation of calciphylaxis, a condition originally described by Selye. The appearance of early skin lesions should be regarded as an indication for subtotal parathyroidectomy. The association of cutaneous gangrene with vascular calcification was first described by Bryandt and White in 1989, and was termed by these authors as 'gangrenous calcification'. A total of 80 cases of this rare complication of chronic renal disease had been reported up to early 1994. A retrospective review of these reports has strongly suggested a close interrelationship between renal failure, secondary hyperparathyroidism, vascular calcification and cutaneous gangrene. The present report concerns a characteristic case to draw attention to this syndrome which is accompanied by serious, predominantly cutaneous, changes.
