Abstract
Prompt identification of Hyperparathyroidism-Jaw Tumor Syndrome (HPT-JT) is vital, particularly for those with a family history or unusual symptoms like progressive facial changes. By employing a thorough diagnostic strategy that includes biochemical tests, imaging, and genetic analysis, we can achieve early diagnosis and effective intervention. In this case, the patient displayed maxillofacial tumors, hypercalcemia, and increased parathyroid hormone levels. Imaging confirmed a parathyroid adenoma, while histopathology showed characteristics of brown tumors. Subtotal parathyroidectomy is the recommended treatment. Additionally, regular follow-ups every 6 months involving biochemical tests and imaging are crucial for ensuring the best patient outcomes.
