Brown tumor of the rib associated with primary hyperparathyroidism misdiagnosed as metastatic deposit - A case report

Abstract

Brown tumor is a rare skeletal manifestation where multiple giant cell rich bony lesions, arise as a direct result of either primary or secondary hyperparathyroidism. It is caused by excess osteoclastic activity and hemosiderin deposition because of uncontrolled parathormone secretion. Brown tumors usually involve mandible, maxilla, clavicle, ribs, and pelvic bones. Our case report describes the case of a 42-year-old lady who consulted our hospital for multiple bony lesions in ribs suspicious of metastasis and summarizes our experience in diagnosis of similar cases that we might come across in the future.
