title: Secondary parathyromatosis in a patient with normal kidney function: review of diagnostic modalities and approaches to management.
abstract: OBJECTIVE
  To present a patient with secondary parathyromatosis, a rare complication of parathyroidectomy, and to discuss issues currently pertinent to its diagnosis and management.
  
  
  METHODS
  Data were derived from clinical and pathologic observations obtained during patient care.
  
  
  RESULTS
  The index patient developed intractable hyperparathyroidism and hypercalcemia that has persisted after 4 surgical procedures and has remained largely resistant to medication, albeit with partial amelioration with combined bisphosphonate and cinacalcet.
  
  
  CONCLUSIONS
  Despite the rarity of this difficult complication of parathyroidectomy, its iatrogenic basis emphasizes a need for heightened awareness and caution among surgeons and endocrinologists. Herein we report an instance of intractable secondary parathyromatosis in a patient with normal kidney function, and we review current approaches to diagnosis and management.
