CASE: A 73-year-old @entity1 with Dukes' C @entity188 , pT3N2bM0, stage IIIB, presented with voiding difficulties including poor stream and terminal dribbling for one   month. The @entity1 was under careful surveillance and had no postoperative recurrence. Physical examination revealed a palpable @entity75 (0.5   *   0.5   cm(2) ) at the @entity546 . He underwent urethroscopy, which showed a cauliflower lesion in the pendulous urethra. Transurethral resection was performed and histopathologic and immunochemical staining demonstrated a metastatic moderately differentiated @entity420 from the colorectal primary. OUTCOME: His voiding disorder improved significantly post-operation and he commenced second-line chemotherapy combined with regional radiotherapy. Follow-up urethrocystoscopy and abdominal computed tomography demonstrated no recurrence or @entity3 . His @entity5 marker remained within the normal range for 12   months. CONCLUSION: Urethral metastasis from primary @entity694 is extremely rare. This disease, with its various atypical presentations, presents a diagnostic challenge to the clinician. In @entity1 with recurrent or persistent lower urinary tract symptoms, further urologic workup including thorough history taking, physical examination, and imaging surveys is warranted.
