Ductal adenocarcinoma of the prostate is a rare variety of the common acinar adenocarcinoma. It usually presents
with obstructive symptoms and at cystoscopy is seen as an exophytic lesion at the area of the verumontanum. It
accounts for less than 1% of all prostate cancers.
We present the case of a 53 year old male who was diagnosed with ductal adenocarcinoma of the prostate
after undergoing elective transurethral resection of the prostate. Immunohistochemistry confirmed the nature of the
tumour. The patient underwent a radical prostatectomy, however histopathology showed extensive extraprostatic
extension.
Men with prostatic ductal adenocarcinoma have a worse prognosis than men with prostatic acinar adenocarcinoma
thus, early diagnosis and aggressive management is indicated, even with low-volume metastatic disease.
