title: Paratesticular rhabdomyosarcoma: a case report.
abstract: OBJECTIVE
  To report a case of paratesticular rhadomyosarcoma and to perform a bibliographic review.
  
  
  METHODS
  We report the case of a 16-year-old male referred to our Department because of a left paratesticular hard tumor with progressive growth. Ultrasound examination showed a paratesticular heterogeneous mass with Internal flow on Doppler.
  
  
  RESULTS
  The patient underwent left inguinal orchiectomy, with pathological diagnosis of rhabdomyosarcoma. He refused adjuvant chemotherapy. After being disease-free for 13 months, he presented with left colic pain. Ultrasound and CT examinations showed a left paraaortic retroperitoneal mass causing grade III ureterohydronephrosis, and lung metastases. Despite rescue chemotherapy treatment, there was no response and the abdominal mass progressed. A surgical approach was not possible since patient showed a rapid clinical worsening leading to his death a few weeks later.
  
  
  CONCLUSIONS
  Paratesticular sarcomas are very uncommon tumors with poor prognosis.
