Brown tumor of hyperparathyroidism with multiple lesions.

Brown tumors are rare focal giant-cell lesions that arise as a direct result of the effect of parathyroid hormone (PTH) on bone tissue in some patients with hyperparathyroidism. Browns tumor is a syndrome associated with an increase in PTH levels by parathyroid glands resulting in hypercalcemia. In the present case report, a 44-year-old female patient presented with a rare case of brown tumor with multiple lesions in the head-and-neck region. The recent advance in various diagnostic and biochemical tests helps in early diagnosis of hyperparathyroidism cases. The dentist should be aware of oral manifestations associated with this type of systemic disease.
