Abstract

Brown tumor is characterized by atypical non-neoplastic bone lesions caused by an accelerated osteoclastic activity and peritrabecular fibrosis due to hyperparathyroidism, resulting in a local damage phenomenon. It is more common in large bones, ribs and pelvis, but can occur in any bone. We describe a case of a 55-year-old woman undergoing hemodialysis for eight years, with development of a lingual mass in the floor of the mouth, which was histologically diagnosed as a brown tumor. Radiological e clinical features are also described. Brown Tumor requires an early diagnosis and multidisciplinary follow up to avoid fractures, deformities and functional alterations.
