title: [Brown tumor as the initial manifestation of primary hyperparathyroidism].
abstract: Brown tumor is a localized form of osteitis fibrosa cystica, being part of the hyperparathyroid bone disease. It rarely is the first manifestation of hyperparathyroidism, since nowadays, the diagnosis is made at an asymptomatic or minimally symptomatic stage. We present a case of a left superior maxillar brown tumor as the first manifestation of primary hyperparathyroidism due to a parathyroid adenoma. A parathyroidectomy was performed, and there was a regression of the bone lesion, without the need of performing other local surgical procedures.
