Localized mandibular enlargement in end-stage renal disease: two case reports and a review of the literature.

Enlargement of the jaws is an infrequently reported complication of chronic kidney disease mineral and bone disorder (CKD-MBD). Two cases of localized mandibular swellings in young patients with histories of end-stage renal disease are discussed with a review of the literature. Although 17 of the first 19 cases that were reported exhibited diffuse enlargement, these reports increase the number of localized swellings to 8 and support the contention that localized expansion of the jaws as a manifestation of CKD-MBD is more common than originally recognized.
