[Renal brucelloma. A rare possible diagnosis].

Presentation of one case of renal Brucelloma in a 61-year old patient. The emphasis is placed in the pathophysiology of the condition and the extraordinary rarity of its renal location. Also an explanation is proposed for the diagnostic methodology and the dissociation, typical in chronic brucellosis, of the different serologic testing. Finally, the increased incidence experimented by this condition in our environment, which involves the reappearance of clinical pictures today thought eradicated, is pointed out.
