Penis metastasis in colon cancer: A case report of an unusual site of dissemination.

Introduction And Importance: Colorectal cancer is a leading cause of cancer-related deaths worldwide. It is estimated that approximately 1.93 million new cases of colorectal cancer were diagnosed and almost one million global colorectal cancer-caused deaths in 2020. The incidence of colorectal cancer has been dramatically rising at alarming rates worldwide in the last decades. The most often sites of metastases are lymph nodes, liver, lung, and peritoneum.

Case Presentation: We present a rare case of a 63-year-old male patient presenting with a nodule in the penis after being treated for cancer in the hepatic flexure of the colon. Biopsy showed colorectal cancer recurrence in the penis.

Clinical Discussion: Metastasis from colorectal cancer to the penis is rare and poorly discussed, with scarce data in the literature.

Conclusion: A high level of suspicion should be adopted for the correct diagnosis and early treatment.
