title: [Penile sarcoma: a rare tumor].
abstract: OBJECTIVE
  We report the case of a penile tumor presenting with lung and lymph node metastasis, with fatal evolution after the absence of response to surgery and adjuvant treatment.
  
  
  METHODS
  Male patient presenting with a penile mass appearing progressively, with metastases.
  
  
  RESULTS
  Partial penectomy and adjuvant chemotherapy were performed, with the appearance of a rapidly growing local recurrence which led to death of the patient in a few months. The tumor was a penile sarcoma with osteosarcomatous differentiation.
  
  
  CONCLUSIONS
  Penile sarcoma is an unfrequent tumor that has a very aggressive behavior, requiring early diagnosis and aggressive management. It has tendency to local recurrence, and when it presents with distant metastases is lethal within a few months.
