Maxillomandibular brown tumor - a rare complication of chronic renal failure

We report a 17-year-old hemodialysis patient with a rapidly growing maxilla ry mass diagnosed as a brown tumor. Although successful control of the para thyroid hormone (PTH) levels was achieved by treatment with vitamin D pulse therapy, the lesion progressed, invaded the maxillary sinus, and caused se vere eating and speech disabilities. No recurrence was observed following s urgical excision. The differential diagnosis and considerations regarding t he causes of the disease in a child, therapy options, and review of the lit erature are presented.
