title: Renal tuberculosis.
abstract: BACKGROUND
  tuberculosis (TB) is a disease with a high incidence and prevalence worldwide. Renal TB is the second most common extrapulmonary form of TB. The purpose of this report is to present the case of a patient with renal TB in order to emphasize the importance of this disease.
  
  
  METHODS
  we report the case of a 30-year-old female who presented with fever, cough, diaphoresis and an abdominal right flank mass. Right hydronephrosis, dilated collector system and loss of renal function were documented. A right nephrectomy was performed. Histopathological exam revealed acid-fast mycobacteria, granulomas and multinucleated Langhans-type giant cells. Renal TB was diagnosed and anti-TB treatment was initiated.
  
  
  CONCLUSIONS
  renal TB is a disease whose incidence has increased in relation to the TB epidemic. Renal TB should be considered in the evaluation of renal masses.
