OBJECTIVE: To report a case of calciphylaxis in a patient with primary hyperparathyroidism without coexistent renal failure.
METHODS: The clinical, laboratory, and radiographic details of this case are reviewed, and the pathogenesis of calciphylaxis and the associated prognosis are discussed.
RESULTS: A 52-year-old woman had progressive fatigue, cachexia, severe osteoporosis, and necrotizing skin lesions. Her serum calcium level was 16 mg/dL, serum phosphorus level was 2.13 mg/dL, and parathyroid hormone level was 2,257 pg/mL (reference range, 15 to 65). On physical examination, gangrenous skin lesions with black crusts were noted on her legs, abdomen, and gluteal region. A mass lesion was detected in the parathyroid region by both ultrasonography and a parathyroid scan. The patient underwent a bilateral neck exploration, and a parathyroid adenoma measuring 3.5 by 1.5 by 1.2 cm was found on pathologic examination. After the operation, biochemical findings normalized, and the skin lesions progressively improved.
CONCLUSION: Severe primary hyperparathyroidism may be a factor leading to calciphylaxis, even in the absence of renal failure and a high calcium-phosphate product. This potentially life-threatening condition should not be left untreated if the levels of serum calcium and parathyroid hormone are severely elevated.
