Extraprostatic Papillary Cystadenocarcinoma of the Prostate
Extraprostatic Papillary Cystadenocarcinoma of the Prostate
A 62-year-old man was evaluated for lower urinary tract symptoms. Imaging studies showed a normal prostate and multiple cysts between the rectum and bladder with no evident communication to the prostate. On pathology, papillary cystadenocarcinoma with positive immunohistochemical staining for PSA was confirmed.
Papillary cystadenocarcinoma of the prostate is an extremely rare tumor, with most of the reported cases originating in Japan. We describe a patient with this unusual neoplasm and review the literature.
