Osteitis Fibrosa Cystica and pathological fractures-the classic but neglected skeletal manifestation of primary hyperparathyroidism: a case report.

Background: Osteitis fibrosa cystica is the classic manifestation of primary hyperparathyroidism (PHPT), occurs after prolonged exposure of bone to high serum parathyroid hormone (PTH) level. It has become increasingly rare due to early detection of PHPT.

Case Presentation: A 37-year-old woman was referred to our institution for fixation of multiple fractures of upper and lower extremities that had been reoccurring in the past 5 years.
