Granuloma Periférico de Células Gigantes como Primeira Manifestação de um Hiperparatiroidismo Primário

Abstract

Primary hyperparathyroidism is a rare disease, due to intrinsic parathyroid pathology, characterised by an excessive parathormone production with subsequent hypercalcemia. It is a disease associated to osseous alterations like bone cyst's or giant cell granulomas and renal, gastrointestinal, neuromuscular and cardiovascular lesions.The authors present a case of primary hyperparathyroidism associated with peripheral giant cell granuloma of oral cavity, as first manifestation. After preliminary histopathological diagnosis of a peripheral giant cell granuloma, the detection of hypercalcemia, elevated PTH and detection of a parathyroid adenoma has lead to definitive diagnosis of first oral lesion as a giant cell granuloma associated to a primary hyperparathyroidism.The fact that the oral cavity is one of the places where these lesions can occur, allows the oral specialist to be one of the keypoints in the diagnosis of a primary hyperparathyroidism preventing the onset of complications of high morbility.
