Brown tumour represents a serious complication of hyperparathyroidism. Differential diagnosis,
based on histological examination, is only presumptive and clinical, radiological and laboratory
data are necessary for definitive diagnosis. Here we describe a case of a brown tumour localised in
the maxilla due to secondary hyperparathyroidism in a young male with chronic renal failure.
Hemodialysis and pharmacological treatment were unsuccessful in controlling secondary
hyperparathyroidism making it necessary to proceed with a subtotal parathyroidectomy. The
proper timing of the parathyroidectomy and its favourable effect on regression of the brown tumor
made it possible to avoid a potentially disfiguring surgical removal of the brown tumor.
