A brown tumor is a giant cell bone lesion that occurs as a complication of hyperparathyroidism. We report a case of mandibular brown tumor associated with primary hyperparathyroidism in a 27-year-old man. Computed tomography (CT) showed a large bilateral tumor in the mandibular region, and biopsy of the mandibular tumor showed a giant cell lesion. The laboratory data showed hypercalcemia and hyperparathyroidism. Contrast-enhanced CT revealed a cystic lesion on the right parathyroid gland. On the basis of these findings, the mandibular tumor was diagnosed to be a brown tumor. Three years 5 months have passed since right parathyroidectomy was performed, and the mandibular bone brown tumors have disappeared bilaterally. Moreover, the progress of the patient has been good.
