Brown tumor in the palate associated with primary hyperparathyroidism.

A case of brown tumor on the hard palate associated with primary hyperparathyroidism is reported. The diagnosis was suggested by the oral findings and clinical history and confirmed by biochemical determinations. Excision of a parathyroid adenoma normalized the metabolic situation and at a one-year follow-up the palatal tumor had diminished in size and lamina dura was partially regenerated.
