Rectal Tropism: An Extremely Rare Case of Prostate Cancer Recurrence With Metastasis to the Rectum Postradical Prostatectomy

Abstract

Prostate cancer is the most common noncutaneous cancer affecting men in the United States. It is a slow-growing tumor that can be missed during the nascent phase. Prostate cancer commonly metastasizes to the bones and nearby lymph nodes. However, cases of metastatic prostate cancer to the rectum are exceptionally rare. Such metastases may cause obstructive or malabsorption symptoms similar to those observed in primary rectal carcinoma. We present a very rare case of prostate cancer recurrence with rectal metastasis in an elderly male with a history of castration-resistant prostate carcinoma status postradical prostatectomy.
