Multiple brown tumors revealing a parathyroid adenoma. About 2 cases.

: A brown tumor is a rare complication of hyperparathyroidism. Its circumstances of discovery are multiple and its symptoms are nonspecific. We report here two cases with deceptive forms of multiple brown tumors discovered in patients with bone pain. It was a parathyroid adenoma in both cases. So, measurement of parathyroid hormone (even in absence of hypercalcemia) should be systematic in every patient with lytic skeletal images.
