Hyperparathyroidism-jaw tumor syndrome (HPT-JT) is a rare hereditary disorder caused by pathogenic gene variants. We report the case of a patient with HPT-JT who carried a novel germline pathogenic variant. A 27-year-old woman presented with thirst, polyuria, fatigue, constipation, and a history of fibro-osseous mandible lesions and endometrial polyps.

Primary hyperparathyroidism (PHPT) is a prevalent clinical condition characterized by an inappropriate secretion of parathyroid hormone (PTH). It is most often caused by one or more parathyroid adenomas, which can, in rare cases, be ectopically located. Ectopic adenomas can pose a diagnostic challenge, lead to treatment delay, and be a common cause of recurrent hypercalcemia after parathyroidectomy.

Tertiary hyperparathyroidism is characterized by hypercalcemia resulting from autonomous parathyroid hormone production and usually occurs after a prolonged period of secondary hyperparathyroidism. This condition can be a complication of X-linked hypophosphatemia (XLH), a rare genetic disease characterized by renal phosphate loss and consequent hypophosphatemia. Parathyroidectomy is considered the first-line therapy but surgical intervention can be complicated by hungry bone syndrome.
