Itis known that the risk of bladder cancer in individuals with spinal cord injury (SCI) and indwelling catheter is higher (over 15 times) than in the general population.However, there are sporadic reports of cancer arising from the suprapubic catheter tract.The presenting symptoms in thesecase reports differ, but it can begin with common urinary symptoms such as dysuria to hematuria.Unless further diagnostic tests such as imaging or cystoscopy is performed, the diagnosis of it could be delayed.Here, we report a unique case of squamous cell carcinoma arising from suprapubic catheter tract in a male with T9 ASIA (American Spinal Injury Association) Classification A SCI with suprapubic catheter for 20 years.He presented with bladder spasm and drainage from the suprapubic site.Abdominal CT scan showed urinary bladder stones.A 3-cm mass was noted adjacent to his suprapubic catheter.A cysto-lithotripsy was performed for removal of bladder stones and resection of the mass.Pathology demonstrated an infiltrating, well differentiated squamous cell carcinoma without clear margins.Bladder and suprapubic tube tract biopsy were performed.Bladder biopsies showed no evidence of cancer;suprapubic tract biopsies showed squamous cell carcinoma.Patient underwent excision of abdominal wall squamous cell mass, suprapubic tract, partial cystectomy, and open suprapubic tube placement.Follow-up cystoscopic surveillance demonstrated no carcinoma over a year after initial resection.Besides using cystoscopy to monitor development of bladder carcinoma in population with chronic catheter, this case raises the awareness that squamous cell carcinoma can also develop from suprapubic tract.Further study is required to explore the mechanism of such development and surveillance techniques.
