Brown tumor, also known as fibrous-cystic osteitis, is rare and terminal stage bony complication of hyperparathyroidism (HPT). It represents a reparative cellular process rather than a real neoplastic lesion. Involvement of the maxillofacial region is rare and if occured, the mandible is the predominantly affected region. The maxillary involvement remains very rare. Radiological evaluation of the lesion should be made in cooperation with clinical history and the laboratory findings.  Here, we present an extremelly rare case of multiple brown tumors localized in bilateral mandible and maxillary sinuses and associated with tertiary HPT in our 30 year old female patient with long standing end stage renal disease (ESRD).

Key words: Brown tumor, tertiary hyperparathyroidism, chronic renal failure
