Answer: C - Brown tumor of hyperparathyroidism occurs with persistent hyperparathyroidism. The condition is similar to central giant cell granuloma and displays osseous lesions that are commonly seen in the mandible, pelvis, clavicle, and ribs. The condition can exist with either primary or secondary hyperparathyroidism. Primary hyperparathyroidism is caused by parathyroid adenoma or hyperplasia and is surgically treated. Secondary hyperparathyroidism is due to low serum calcium and treated with vitamin D and/or renal transplantation.
