Postoperative Hyperparathyroidism in Differentiated Thyroid Cancer

Abstract

The coexistence of non-medullary thyroid carcinomas and primary hyperparathyroidism is very rare. The incidental diagnosis of thyroid carcinomas during or after the treatment of parathyroid disease, mostly in the pathology specimens, is common. However, parathyroid adenomas detected after total thyroidectomy may represent a clinical and diagnostic problem. In this chapter, a patient with parathyroid adenoma diagnosed after total thyroidectomy is reported with an emphasis on differential diagnosis of residual neck lesions and clinical awareness of concomitant thyroid and parathyroid pathologies.
