title: [Imitation of metastatic lesions in patients with brown tumor].
abstract: The authors have presented two cases of hyperparathyroidism in male patients at the age of 52 and 77 years in whom radiological findings imitated osteolytic, metastatic bone lesions. It has been emphasised that the difficulties with proper diagnosis of brown tumor often occur and the final diagnosis is based on the exact pathology test. In patients with pathological fracture resection with margins and intramedullary fixation, as well as total hip replacement were performed. Postoperative observation revealed that the pain and radiological changes stopped after parathyroid gland resection as the main reason of the brown tumor. The authors have confirmed that open biopsy should be a routine procedure in patients with suspicion of brown tumor.
