A patient with end-stage renal disease, hemodialysis treatment, severe
secondary hyperparathyroidism and mandibular brown tumor received inc
reasing doses of oral calcitriol (3,5 to 9 mu g/week) and calcium carb
onate (10 g/day). Nineteen months after the treatment, clinical, radio
logical and humoral improvement were observed. The present case demons
trates the effectiveness of medical parathyroidectomy for the control
of severe secondary hyperparathyroidism -brown tumor- in chronic hemod
ialysed patients. This procedure should be considered as choice treatm
ent keeping surgical parathyroidectomy for cases in which it is contra
indicated such as hyperphosphoremia and/or controlled hypercalcemia or
failure of the former procedure.
