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.

Highlights

Colorectal carcinoma is a common malignancy affecting large demographic of populations across the world
We present a rare case of such metastasis mimicking priapism, resulting in acute urinary retention
The clinical manifestation associated with penile metastasis are as acute urinary retention, priapism, penile nodules, skin nodules, generalize swelling, and oedema [3]

Summary

Introduction

Colorectal carcinoma is a common malignancy affecting large demographic of populations across the world. Penile metastasis of colorectal cancer has clinical manifestation, such as penile nodules, priapism, urinary retention, and skin nodules. Presentation of skin nodules and priapism are exceptionally rare [4] [5]. We present a rare case of such metastasis mimicking priapism, resulting in acute urinary retention. Penile metastasis of colorectal carcinoma is a rare phenomenon in clinical setting. They normally manifest as penile lesion and acute urinary retention. 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. Urinary drainage followed by further cancer intervention or palliative care is crucial for effective management
