Abstract
Primary hyperparathyroidism is an endocrine disorder occurring due to increased secretion of parathormone resulting in clinical, anatomical, and biochemical alterations. On the other hand, excision of a parathyroid adenoma can normalize the metabolic status. Brown tumors represent the terminal stage of the remodeling processes during primary or secondary hyperparathyroidism. They are erosive bony lesions caused by rapid osteolysis and peritrabecular fibrosis, resulting in a local destructive phenomenon. Facial skeleton is involved in about 2% of all cases of which the mandible is frequently affected. We report a case series of four patients who presented with brown tumor of both maxilla and mandible. A complete assessment of the medical history, blood investigations and radiological findings combined with biopsy results is necessary for a correct diagnosis. The standard treatment of the Brown tumors is not a surgical resection, but the treatment of the cause of the tumor, which in this case is hyperparathyroidism. However in our case, the extent of the lesion and the non resolution after the parathyroidectomy necessitated a surgical approach in two of our patients however two responded well to medical management alone.
