A case report of squamous cell carcinoma in a suprapubic urinary catheter tract: surgical excision and simultaneous colostomy formation

Abstract

Squamous cell carcinoma (SCC) arising from a suprapubic cystostomy tract is a rare complication of long-term suprapubic catheterization (SPC). A 53-year-old man with paraplegia secondary to spina bifida presented with a painful granulomatous lesion around his SPC site that was being treated with silver nitrate cauterization in the community. Consequently, he developed a sacral pressure sore due to reduced mobility from the pain. He also had increasing difficulties with defaecation secondary to his spina bifida. His sacral pressure sore was secondary to a cryptoglandular fistula with coccygeal osteomylelitis. Post-operative pathology revealed infiltrative SCC involving full thickness of the specimen from skin to the bladder wall with clear surgical margins. We describe the first case requiring a simultaneous suprapubic tract SCC excision and colostomy formation. We recommend early investigation of lesions arising from a long-term suprapubic tract especially in patients with spinal cord injuries or congenital defects.
