Surgical Approach to Primary Hyperparathyroidism in Patients with Concomitant Thyroid Diseases: A Retrospective Single Center Study.

Background: Primary hyperparathyroidism (PHPT) and thyroid diseases are a frequent concomitant occurrence, but the surgical approach to associated disease is still debated.

Methods: We retrospectively evaluated a series of PHPT patients focusing on thyroid disease and surgery.

Results: Among 238 PHPT patients undergoing parathyroidectomy (PTX) between 2002 and 2017, 128 were affected also by a benign thyroid disease, namely, goiter in 118 (76 multinodular (MNG) and 42 uninodular (UNG)), autoimmune thyroiditis in 10, and hyperthyroidism in 21.
