We present a case report of a 49 year old patient with a known history of rectal adenocarcinoma treated with extended abdominal perineal resection. After five the patient was diagnosed with metastases to the prostate gland. This case stands out not only due to the infrequency of an onset of a colorectal tumor in the prostatic gland but also the late onset of the tumor. In these cases the differential diagnosis between a metastatic tumor and a primary urologic tumor is difficult due to similar morphology and histology, making the CDX-2 immunohistochemical maker expression an important tool to define the histopathology of the tumor.
