Description

A 71-year-old man with gross hematuria and urinary retention showed a 7×8 cm polycystic mass compressing the prostate on the right ventral side on pelvic magnetic resonance imaging (MRI). The prostate specific antigen (PSA) level was 6.47 ng/ml. Prostate biopsy histopathology was consistent with prostate ductal carcinoma. Considering the difficulty of surgical therapy, endocrine therapy was undertaken prior to surgery for seven months. Almost all of the cyst disappeared ; robot-assisted laparoscopic radical prostatectomy was then successfully performed. Prostate ductal carcinoma is a relatively rare pathology for which radical prostatectomy plays an important role if the disease is localized. However, when ductal carcinoma involves large cysts, surgical treatment may be difficult. This report discusses the usefulness of neoadjuvant endocrine therapy to reduce the size of the cystic lesions.
