[Ductal carcinoma of the prostate with multilocular cystic formation].
A 72-year-old man was admitted to our department with the complaint of nocturia. PSA was elevated to 18.2 ng/ml. Transrectal ultrasonography, CT scan and MRI showed multilocular cystic lesions at the posterior site of the prostate, with rectal and bladder invasion and lymph node metastasis. Transrectal needle biopsy of the prostate and fluid aspiration of the prostatic cyst were performed. The aspirated fluid was bloody, but the result of cytology was negative. Histopathological examination of the needle biopsy specimen revealed ductal carcinoma of the prostate. We diagnosed this case as a T4N1M0 prostatic cancer, and started endocrine therapy. Thirty-nine cases of adenocarcinoma of the prostate with cystic formation in the Japanese literature are reviewed.
