Parathyroid Gland Carcinoma
Definition 1
A malignant tumor arising from the parenchymal cells of the parathyroid gland. It is associated with the symptoms of primary hyperparathyroidism, resulting from the excessive production of parathyroid hormone. Morphologically, the differential diagnosis from parathyroid gland adenoma may be difficult. A definitive diagnosis of carcinoma is made only in the presence of capsular invasion, vascular invasion, and/or perineural invasion. (NCI Thesaurus)
Definition 2
A rare cancer that forms in tissues of one or more of the parathyroid glands (four pea-sized glands in the neck that make parathyroid hormone, which helps the body store and use calcium). (NCI Dictionary)
