Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Syed Musadiq Ali M.B.B.S.[2]

A single parathyroid adenoma is responsible for 80% to 85% of hyperparathyroidism^[1]. A double adenomas the culprit in 4% to 5%, and parathyroid hyperplasia in 10% to 12%^[2]. Parathyroid carcinomas are very rare causes of hyperparathyroidism and account for less than 1% of disease. Adenomas are most common in patients 50 to 70 years old.They can occur at any age. Women are affected 3-times as often as men

• Parathyroid carcinomas are very rare causes of hyperparathyroidism and account for less than 1% of disease.
