ABSTRACT: Background: Penile metastasis of colorectal carcinoma is a rare phenomenon in clinical setting. They normally manifest as penile lesion and acute urinary retention. However, presentation of priapism is exceedingly rare. Aims: Discussion of this rare presentation as well as the diagnostic processes and subsequent management. Case Presentation: A 54-year-old male with a history of colorectal cancer presents with acute urinary retention. Examination of the patient demonstrates a semi-erect penis, with multiple palpable nodules on the shaft and penile meatus. Histological and imaging findings indicate penile metastasis of colorectal cancer. Conclusion: Biopsy via cystoscopy is used to obtain definitive diagnosis of penile metastasis. Urinary drainage followed by further cancer intervention or palliative care is crucial for effective management.
