[Brown tumors in chronic hemodialysis patients].

Purpose: Brown tumors are rare and severe manifestations of secondary hyperparathyroidism. We propose in this study: to define and illustrate brown tumors observed in our hemodialysis center; to show the frequency for 20 years in our center; to identify risk factors compared to the rest of dialysis patients; and finally to offer improved support for reducing the incidence.

Patients And Methods: We conducted a retrospective and descriptive study, over a period of 20 years (1993-2013), including 311 cumulative patients which are chronic hemodialysis in our unit.
