A case of normocalcemic primary hyperparathyroidism presenting with a mass in the oral cavity and accompanying incidental papillary thyroid carcinoma

Abstract

Hyperparathyroidism (HPT) is an endocrine disorder characterized by high secretion of parathyroid hormone. Brown tumor is one of the skeletal manifestations of HPT. Its overall prevalence is low (about 0.1%). Involvement of facial bones is extremely rare. The mandible is involved in 4.5% of cases. Primary HPT (PHPT)with vitamin D deficiency worsens the clinical course. Parathyroid adenoma is detected in ectopic places with a rate of 8.5%. 0.2% is intrathyroidal, 2% is located in different neck regions, 4.1% is in the upper mediastinum, and 2.2% is in the lower mediastinum. The prevalence of papillary thyroid cancer (PTC) in PHPT patients has been reported to range from 2% to 15%. In the literature, incidentally detected papillary thyroid cancer in patients with hyperparathyroidism was detected in patients who underwent total thyroidectomy associated with intrathyroidal parathyroid adenoma. In this article, we present a case of incidental papillary thyroid carcinoma with ectopic parathyroid adenoma accompanied by severe vitamin D, and diagnosed during accompanying surgery following a brown tumor was considered after primary hyperparathyroidism was detected. However, the patient was admitted with a mass in the oral cavity, diagnosed before as a pyogenic granuloma with a delayed diagnosis without considering brown tumor because it was normocalcemic. It is the first case in the literature of papillary thyroid carcinoma detected incidentally with ectopic parathyroid adenoma in the thyrothymic region.
