Note 3: The number of parathyroid glands differs among individuals; however, most people have two superior and two inferior parathyroid glands.

Note 4: Parathyroid carcinoma develops within the parathyroid gland itself, and the location of the carcinoma is dependent on the embryologic descent and location of the affected gland.
