title: [Prostatic ductal carcinoma].
abstract: OBJECTIVE
  We presented one case of prostatic adenocarcinoma of ductal origin, known as endometrial adenocarcinoma before. The first case was published in 1967 by Mellicow. Since then we could only recover 8 cases by spanish authors.
  
  
  RESULTS
  61-year-old patient presenting with urethral bleeding, PSA 12 ng/cc, and an exophytic urethral mass. Histology was compatible with ductal adenocarcinoma of the cribiform type. Radical prostatectomy was carried out with good outcome at six months follow up.
  
  
  CONCLUSIONS
  Prostatic ductal adenocarcinoma is a rare tumor, accounting for 0.2-5% of prostatic tumours. Its behaviour is variable, similar to the acinar cell type. Strikingly, there are scarce references to this tumor type; accordingly to the statistics of incidence it should have been referred more often, which would help to its study in terms of outcomes, treatment, and prognosis.
