Abstract:

Brown tumors (osteitis fibrosa cystica) are non-neoplastic lesions caused by abnormal bone metabolism due to hyperparathyroidism. It is often accompanied by secondary hyperparathyroidism, it is more rare to accompany primary hyperparathyroidism. The Brown tumor is often seen in the ribs, clavicle and pelvis, but may involve any bone in the skeletal system, including maxillofacial bones. The mandible is held more frequently than the maxilla in the chin area. They are clinically smooth, soft and bone destructive lesions. These lesions may mimic malignancy clinically and radiologically. While there is a common view of the intervention of the parathyroid glands that cause Brown tumor treatment, there is no consensus regarding the intervention for Brown tumor. In this article, four Brown tumor cases secondary to primary hyperparathyroidism that cause mass lesion in the oral cavity and our approach to cases are discussed in the light of the literature.
