Abstract

Background: Brown tumor is a giant cell focal bone lesion associated with hyperparathyroidism and is more common in long bones such as the femur, ribs, pelvis, and clavicle, rather than in the head and neck region. Brown tumors occur less frequently in patients with primary hyperparathyroidism and are not usually a diagnostic marker of the disease. In addition, when primary hyperparathyroidism shows normocalcemic values and this disease is accompanied by multiple sclerosis, diagnosis becomes difficult.
