Calciphylaxis on Technetium Bone Scan: Two Case Reports

Calciphylaxis is a rare but feared condition thought to related to derangements in calcium and phosphorus metabolism. The syndrome has a predilection for obese women receiving dialysis for chronic renal failure (1, 2). Patients develop painful violaceous lesions in the subcutis, which can lead to ulceration and wound-related sepsis. In severe cases, amputation is required for the gangrenous involved extremity (3). We present two cases of calciphylaxis with similar clinical presentations and physical findings.
