title: Cutaneous gangrene, vascular calcification, and hyperparathyroidism.
abstract: We describe the development of necrotic ulcers with underlying vascular calcification in a 72-year-old man who had chronic renal failure. These lesions had surrounding ecchymoses. The patient had a normal serum calcium concentration, an elevated parathyroid hormone level, and findings consistent with a parathyroid adenoma on ultrasonography. We consider this another case of a characteristic cutaneous syndrome secondary to underlying vascular calcification and hyperparathyroidism.
