title: [Primary hyperparathyroidism presenting as a brown tumor of the maxilla and hard palate. Apropos of a case].
abstract: Significant controversy persists in the classification of giant cell lesions of the maxillofacial skeleton. Multifocal giant cell lesions are strongly suggestive of hyperparathyroidism brown tumors. Maxillary localization is extremely rare. We report a case of primary hyperparathyroidism manifesting in the form of giant cell tumors of the maxilla, the hard palate and long bones. Biochemistry confirmed the diagnosis. Computed tomography localized the parathyroid tumor at the cervicothoracic junction in the retrosternal area. We discuss the clinical features of skeletal involvement in primary hyperparathyroidism and stress the need for ionized serum calcium assay in case of giant cell tumors of the cranial bones.
