Jaw Tumor: An Uncommon Presenting Manifestation of Primary Hyperparathyroidism Jaw Tumor: An Uncommon Presenting Manifestation of Primary Hyperparathyroidism

چکیده
Introduction: To report two unusual cases of primary hyperparathyroidism (HPT) that initially manifested with a “ jaw tumor” and to discuss the clinical implications of a giant cell granuloma vs an ossifying fibroma of the jaw. Material and methods: The history, physical examination, laboratory values and the imaging and pathologic findings are described in two patients who presented with a “jaw tumor” and were subsequently diagnosed with primary HPT. The diagnosis and management of osteitis fibrosa cystica and HPT-jaw tumor syndrome are reviewed. Results: Patient #1 was a 70-year-old male who presented with hypercalcemia, severe jaw pain, and an enlarging mass in his mandible. Biopsy of the mass revealed a giant cell tumor and he was subsequently diagnosed with primary HPT. A sestamibi scan demonstrated a single focus of abnormal radiotracer accumulation, corresponding to a 13,470 mg parathyroid adenoma, which was resected. Postoperatively, the serum calcium normalized and the giant cell granuloma regressed spontaneously. Patient #2 was a 36-year-old male with four incidentally discovered tumors of the mandible and maxilla, who was diagnosed with normocalcemic HPT and vitamin D deficiency. Biopsy of one of the tumors revealed an ossifying fibroma. Bilateral neck exploration revealed a 2480 mg right inferior parathyroid adenoma, which was resected. Postoperative genetic testing revealed an HRPT2 gene mutation. He subsequently underwent resection of an enlarging ossifying fibroma of the mandible with secondary reconstruction. Conclusions: A “jaw tumor” in a patient with primary HPT may be a manifestation of osteitis fibrosa cystica or HPT-jaw tumor syndrome underscoring the importance of biopsy and genetic testing for management and follow-up.

Primary hyperparathyroidism presenting as a giant cell tumor of the jaws.
OBJECTIVE Giant cell tumors of the maxillofacial skeleton are uncommon, they are usually late manifestation of primary hyperparathyroidism. A series of five clinical cases in four women and one man presenting as the giant cell lesions in the maxilla and/or mandible are discussed. METHODS Biopsy of the lesions, biochemical and hormonal analyses, densitometry and parathyroid scintigraphy were c...

Primary hyperparathyroidism (PHPT) is not an uncommon endocrine disorder. We describe a patient with PHPT who presented with progressive proximal limbs weakness and dystrophic changes of leg muscles. Serum calcium, alkaline phosphatase, and parathyroid hormone were elevated and serum phosphorus was low. Neck computerized tomography scan showed a parenchymatous tumor in the right lobe of the thy...
متن کاملSuccessful Treatment of Osteitis Fibrosa Cystica from Primary Hyperparathyroidism
Osteitis Fibrosa Cystica (OFC) is defined as the classic skeletal manifestation of advanced primary hyperparathyroidism. With the increased detection by means of routine calcium screening, the clinical profile of primary hyperparathyroidism in Western countries has shifted from symptomatic disease to one with subtle or no specific symptoms ("asymptomatic" primary hyperparathyroidism). The autho...
متن کاملPrimary hyperparathyroidism-jaw tumor syndrome: a confusing and forgotten diagnosis
BACKGROUND Primary hyperparathyroidism is caused by the excessive growth of parathormone secretion, its consequence being hypercalcemia. The parathyroid adenoma is responsible for over half of primary hyperparathyroidism cases. The mandibular tumor can be the initial sign in the case of primary hyperparathyroidism. CASE PRESENTATION We present the case of a 33 year old patient with history of...
