Oral and Maxillofacial PathologySalivary heterotopia of the parathyroid gland: A report of two cases and review of the literature
Section snippets
Materials and methods
The records of the Department of Pathology, Long Island Jewish Medical Center, were searched over a 4-year period (1/1/1998 to 1/1/2002). All cases in which the final pathology report contained a reference to “parathyroid” were identified.
Results
Of a total of 111,414 surgical accessions, 759 specimens containing parathyroid tissue were identified. Of these 759 cases, 2 (0.26%) contained foci of ectopic salivary gland tissue.
Discussion
Two cases of heterotopic salivary gland tissue of the parathyroid gland area that occurred in relation to both the superior and inferior parathyroid glands are presented. This represented 0.26% of all parathyroid gland–containing surgical specimens accessioned at our institution over a 4-year period. In both cases, cyst formation was noted adjacent to the heterotopic salivary gland tissue.

Conclusion
While heterotopic salivary gland tissue has been described in a number of different anatomic locations, its occurrence in relation to the parathyroid glands is quite uncommon. We describe 2 cases of heterotopic salivary gland tissue of the parathyroid gland area. This represents only 0.26% of all parathyroid gland–containing surgical specimens accessioned at our institution over a 4-year period.

2012, Human PathologyCitation Excerpt :The authors were not able to determine if the tissue was ectopic salivary gland tissue or if it had developed through a metaplastic process [14,15]. Ectopic salivary gland tissue—normal salivary gland tissue located in an abnormal anatomical location—has been described in areas as diverse as the anterior cheek, lower anterior sternocleidomastoid muscle, parathyroid, muscles of the tongue, mandible, middle ear, pituitary, mediastinum, prostate, vulva, and rectum [16-21]. As with all ectopic tissues, ectopic salivary gland tissue can undergo neoplastic transformation, with Warthin tumors and pleomorphic adenomas being the most commonly described neoplasms [17,19-21].
