Abstract

Brown tumor is a histologically benign lesion that is a serious complication of renal osteodystrophy because it may result in severe deformity and discomfort. We report a case of brown tumor, which occurred in a 35-year-old woman with chronic renal failure, who had been treated with hemodialysis for 14 years. The lesion was found on the lingual side of the mandible. Standard panoramic radiograph showed generally decreased bone mineral density, loss of lamina dura, and thin cortical plates. Computed tomography (CT) revealed multilocular expansile lesions with heterogeneous attenuation in the anterior mandible, as well as generalized trabecular alteration with homogeneous sclerosis, and thinning or obliteration of cortical plates. Excision of the mandibular lesion and curettage of the affected bone were performed. (Korean J Oral Maxillofac Radiol 2008; 38: 229-31)
