Hyperparathyroidism is characterized by the overproduction of parathyroid hormone (PTH). Hyperparathyroidism can be Primary, secondary and tertiary, In all these forms of hyperparathyroidism there is osteoclast mediated bone resorption which is caused by excess Parathyroid hormone levels that produce bone lesion called brown tumor of hyperparathyroidism. Brown tumor of Hyperparathyroidism is a benign non-odontogenic giant cell lesion of jaw with multinucleated giant cells. The term brown tumor is derived from the brown color of lesion as seen on surgical exploration. The characteristic discoloration is result of hemosiderin production. The brown tumor regress usually after hyperparathyroidism has been successfully corrected. Its surgical excision is usually not recommended until lesion is large symptomatic, at a risk of pathological fracture and recurrence.
