Abstract:

Introduction:Primary hyperparathyroidism due to parathyroid adenoma commonly causes raised serum calcium and focal giant cell lytic lesions in bones known as Brown’s tumors. It is more common in females in the post-menopausal age group.Case Report:We report a case of a 29-year-old female patient with Brown’s tumor maxilla in a clinical setting of normocalcemic primary hyperparathyroidism. The patient presented to us with facial and palatal swelling for which FNAC was done. Cytology revealed hemosiderin-laden macrophages suspicious for Brown’s tumor. On further imaging studies such as CT Neck, Tc99 Sestamibi scan, and other biochemical tests like parathyroid hormone assay and serum calcium level, the diagnosis of a hyperfunctioning parathyroid gland with normal calcium level was made. Parathyroidectomy was performed and parathyroid adenoma came out to be the primary pathology. On post-operative follow up there was regression of the swelling on the face and palate relieving the patient symptomatically.Conclusion:The diagnostic suspicion of primary hyperparathyroidism should be kept in mind whenever a young female presents with suspected Brown’s tumor, even with normal serum calcium levels, for appropriate management. Ours was a highly uncommon case that was a diagnostic challenge and had a successful treatment outcome. Very few such cases have been reported in the literature to date to the best of our knowledge.
