Abstract

Ectopic parathyroid adenomas are rare and usually present with biochemical hyperparathyroidism. They most frequently occur in the mediastinum or thymic region. Localization within a lymph node along the recurrent laryngeal nerve chain is extremely rare. We report a case of a 70-year-old woman in whom a non-functioning ectopic parathyroid adenoma was incidentally discovered within a lymph node of the right recurrent laryngeal nerve chain during surgery for a suspicious thyroid nodule. Histopathology and immunohistochemistry confirmed the parathyroid origin. This case highlights an unusual localization and the diagnostic challenges associated with non-functioning parathyroid adenomas.
