Prostatic ductal adenocarcinoma: an unusual case of a rare prostate cancer

Rayan El Hassan, John Corr, Rajiv Pillai


A 65 year old gentleman was referred with symptoms of haematuria and haematospermia in association with an elevated prostate specific antigen (PSA). He was investigated with a flexible cystoscopy, Ultrasound scan and a computed tomography (CT) of his abdomen and pelvis. These failed to reveal any abnormality. Magnetic resonance imaging (MRI) revealed a Prostate Imaging Reporting and Data System PIRADS 2 lesion in the left peripheral gland and PIRADS 3 lesion on the right side posterolaterally at the level of mid gland of the prostate. He went on to have Transrectal ultrasound biopsies of his prostate (TRUS Bx) that excluded any pathology. On follow up visits his PSA continued to rise and he underwent Template biopsies of the prostate. The histological features had no evidence of any Prostatic intraepithelial carcinoma (PIN) or other malignancies. Flexible cystoscopy was repeated due to his persistent haematospermia. This showed prominent papillary lesions over his verumontanum and prostatic urethra. Biopsies from these areas revealed Ductal Adenocarcinoma of the Prostate (DACP). A subsequent staging MRI revealed unchanged appearance of the PIRADS2 nodule. There was however some low signal extending into the right seminal vesicle which is more pronounced than on the previous scan reported as PIRADS3. Subsequent mapping Template biopsies and Transurethral biopsies revealed a Gleason 4+4 DCAP. A staging CT and bone scan excluded any metastasis. He went on to receive an open radical prostatectomy and pelvic lymph node dissection as a curative treatment for his locally advanced disease.
