Recurrent secondary hyperparathyroidism due to implanted parathyroid tissue: a case report.

Abstract

Hyperparathyroidism is a common complication of chronic renal failure. Although many patients can be managed by conservative measures, surgery is sometimes necessary. One of two operations can be performed: subtotal parathyroidectomy or total parathyroidectomy with reimplantation of parathyroid tissue into muscle. A case is presented of a patient who underwent the first and then the second of these procedures for recurrent hyperparathyroidism. A further recurrence was found to be caused by the implanted parathyroid tissue in a forearm muscle, requiring a third procedure for control of the disorder.
