Multiple brown tumors in the course of primary hyperparathyroidism mimicking bone metastases – case report

Abstract

Brown tumours (especially multiple) are uncommon manifestations of primary hyperparathyroidism (PHPT) in developed countries. Although PHTP can cause various symptoms, it can often be mistaken for malignancy. The disease itself (although curable) can lead to disabilities and other serious complications. Herein we report the case of a 65-year-old patient with multiple brown tumours as a very rare first manifestation of normocalcaemic form of primary hyperparathyroidism caused by a giant parathyroid adenoma.
