Localized Jaw Enlargement due to Fibrous Dysplasia

Osteitis fibrosa is a well documented complication of hyperparathyroidism secondary to chronic renal failure. It preferentially affects the long bones, the spine and the ribs. Maxillofacial bones are rarely affected and leads to facial deformities. We report the case of a 15-year-old female patient who developed hyperparathyroidism secondary to end-stage renal disease that manifested as unilateral jaw enlargement. Histological appearance is that of a fibrous dysplasia.
