title: Synchronous occurrence of parathyroid carcinoma and adenoma in an elderly woman.
abstract: The simultaneous occurrence of parathyroid carcinoma and other pathologic conditions of the parathyroid on a sporadic basis is extremely rare. Parathyroid exploration in an otherwise healthy 78-year-old woman with no underlying risk factors revealed synchronous right upper parathyroid adenoma and left upper parathyroid carcinoma. The patient's modest hypercalcemia (11.5 to 12.3 mg/dl) was seemingly at variance with remarkable parathormone elevations of 30 to 70 times normal.
