Salivary heterotopia of the parathyroid gland: A report of two cases and review of the literature

Two cases of periparathyroid salivary gland heterotopia are described. A review of the records of the Department of Pathology, Long Island Jewish Medical Center, over a 4-year period, identified 759 surgical specimens containing parathyroid gland tissue. Of these, 2 (0.26%) contained foci of ectopic salivary gland tissue. Both cases were associated with cyst formation. To date, 9 additional cases of heterotopic salivary gland tissue associated with the parathyroid gland have been described in the literature.
