Brown tumors are more common in patients with primary hyperparathyroidism, however, due to the increased prevalence of secondary hyperparathyroidism, there are more brown tumors from secondary hyperparathyroidism than form primary hyperparathyroidism. It is difficult to differentiate a Brown Tumor from a giant cell tumor or fibrous dysplasia; however, other signs of hyperparathyroidism should be present.
