title: [Pelvic actinomycosis: a case with secondary localization in the liver].
abstract: BACKGROUND
  Actinomycosis is uncommonly observed in a pelvic localization. The presence of an intrauterine device is an important risk factor.
  
  
  METHODS
  A 50-year-old woman presented a tumoral mass in the pelvis with secondary liver involvement. Pathology examination corrected the initial diagnosis of advanced stage pelvic neoplasia to actinomycosis. Rapid improvement was achieved with penicillin.
  
  
  CONCLUSIONS
  Differential diagnosis is difficult but essential in case of pelvic actinomycosis as misdiagnosis can have disastrous surgical consequences. Medical treatment is indicated. Actinomycosis should be entertained as a possible diagnosis in all cases associating a pelvic tumor and inflammation in women wearing an intrauterine device.
