Metastatic colon carcinoma to the prostate gland.

We present a case report of a 70-year-old man with a known history of sigmoid adenocarcinoma, treated with chemotherapy and surgical resection of synchronous lung metastases. Four years after initial diagnosis, the patient was diagnosed with metastases to the prostate gland, proven pathologically. To our knowledge, colon adenocarcinoma metastasizing to the prostate has not been previously described on magnetic resonance imaging and positron emission tomography-computed tomography.
