RESUMO
This report describes the case of a 42-year-old woman who consulted with a maxillofacial specialist for pain and an exophytic lesion in the maxilla. Biopsy examination disclosed a bone cyst with abundant giant cells, and head and neck computed tomography was performed. A diagnosis of brown tumor in the maxilla and mandible was made, and primary hyperparathyroidism (parathyroid adenoma) was determined as the origin of the bone lesions. The patient underwent a left superior parathyroidectomy, which resolved the hormonal disorder (as determined by normal calcium and parathyroid hormone levels) and the brown tumors, which appeared to have mineralized at 1-year follow-up computed tomography. Dental implant rehabilitation was performed at the sites of the absent tumors. A systematic review of articles published in the English-language medical literature through the PubMed and Medline databases yielded 40 articles (published from 1969 through 2016) on 45 cases of hyperparathyroidism associated with the location of a brown tumor in the mandible or maxilla.
