Chronic parathyroiditis associated with parathyroid hyperplasia and hyperparathyroidism

Abstract

Two cases of chronic parathyroiditis associated with parathyroid hyperplasia and hyperparathyroidism are described. There was no evidence of an underlying infectious disease, a developmental anomaly, or a drug reaction that could explain the inflammatory component. It is suggested that an autoimmune process might have been involved in the pathogenesis of this previously unreported clinicopathologic entity.
