OBJECTIVES: 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. METHODS/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.
