Brown Tumors are rare benign tumors that are considered to be the end manifestation of hyperparathyroidism. They can be clinically identified as localized palpable masses in any part of the skeleton. Radiological features vary according to the extent of hyperparathyroidism. In this case report, we present a 24-year-old male on haemodialysis for end stage renal disease, with brown tumor of the mandible and maxillary alveolus as a consequence of longstanding secondary hyperparathyroidism.
