Evolution of maxillofacial brown tumors after parathyroidectomy in primary hyperparathyroidism.

Background: Brown tumor occasionally affects the facial bones. Clinically, these lesions can be mistaken for a neoplasm. Opinions are divided on the course of management of the bony lesions once parathyroidectomy has been carried out.

[Partial pharyngolaryngectomies for treatment of pharyngolaryngeal cancer].

Background: We undertook this study to evaluate the results obtained with conservation therapy of the larynx in patients with laryngopharyngeal epidermoid carcinoma.

Methods: Patients with stages I and II epidermoid cancer of the larynx and pharynx were included. All patients were evaluated endoscopically, functionally, and with cervical tomography.

[Multiple maxillofacial brown tumors as primary hyperparathyroidism manifestation].

Objective: In order to analyze the differential diagnosis of giant-cell lesion in facial bones, we present a case of a patient without a previously diagnosed primary hyperparathyroidism that displayed multiple maxillofacial brown tumors as the initial clinical manifestation of the disease.

Case Description: A 70 year-old female with amandible tumor and one year of disease progression. Tumor biopsy confirmed the presence of a giant-cell lesion.
