Abstract Multiple osteolytic lesions are usually associated with bone metastasis. However, brown tumor should also be included in the differential diagnosis. Brown tumor is a rare benign lesions in skeletal system, encountered in patients with uncontrolled primary or secondary hyperparathyroidism. In our case report, we present a 35 - year - old female with multifocal brown tumor that difficultiy in differential diagnosis of metastasis of malignant parathyroid.
