title: Urachal adenocarcinoma. Case report and bibliographic review.
abstract: OBJECTIVE
  Literature review of adenocarcinoma of the urachus in connection with two cases recently diagnosed and treated in our center.
  
  
  RESULTS
  We report 2 cases of urachus Adenocarcinoma treated in our institution, both underwent extended partial cystectomy including excision of the urachus up to the umbilicus.
  
  
  CONCLUSIONS
  Urachal adenocarcinoma is an exceptional tumor, of poor prognosis, the treatment of which is surgical (partial cystectomy), and the main  predictors of disease-free survival are the degree of tumor differentiation and the free margins of the surgical specimen.
