A brown tumor is a non-neoplastic lesion resulting from an abnormality of bone metabolism in the context of hyperparathyroidism. We report the case of a 51-year-old woman who initially consulted for edentulism and a growing mandibular mass. She benefited from a radiological and biological assessment which made the diagnosis of primary hyperparathyroidism combined with a parathyroid adenoma. We remind through this observation the difficulty to establish a correct diagnosis in patients with an osteolytic process of the maxilla and the necessity to look for hyperparathyroidism in front of a giant cell lesion given the insidious character of this endocrinopathy.
