Bone tumors in the maxilla and the tibia leading to the diagnosis of asymptomatic primary hyperparathyroidism in a 17-year-old male: A case report.

introductionPrimary hyperparathyroidism is a common endocrine disorder, especially among postmenopausal women, characterized by elevated calcium levels and excessive secretion of parathyroid hormone due to hyperactive parathyroid glands. PRESENTATION OF CASE: A 17-year-old male presented with a painless mass in the maxilla, which developed six months after a cystic lesion was diagnosed in his right knee. Subsequent examinations identified a parathyroid tumor, leading to surgical excision of the right lower parathyroid gland, and the patient developed hypocalcemia postoperatively, indicative of Hungry Bone Syndrome. DISCUSSION: Primary hyperparathyroidism occurs mostly in females aged 50 to 60 and presents with many clinical symptoms and signs, but our patient was a 17-year-old male and had one of the complications of this disease, which is a brown tumor, without the appearance of the common typical symptoms of the disease, which led to excluding the diagnosis of a brown tumor and suspecting a giant cell tumor due to the histological similarity.

conclusionThis case report emphasizes the critical need to consider primary hyperparathyroidism in atypical demographics, such as young males. Notably, the formation of a brown tumor prior to overt hyperparathyroidism symptoms suggests potential early complications. This case reinforces the importance of surgical expertise in successful parathyroidectomy in countries without advanced imaging.
