Background Patients with spinal cord injury and a chronic indwelling urinary catheter are known to have an increased risk of bladder malignancy. However, squamous cell carcinoma (SCC) of the epidermis around a suprapubic cystostomy is relatively rare. Here, we report a case of lower abdominal SCC arising from the suprapubic cystostomy tract. Case presentation A 58-year-old man with a complete spinal cord injury was referred to our hospital with a chief complaint of an abdominal mass. Abdominal enhanced computed tomography (CT) showed a 7-cm mass surrounding the suprapubic cystostomy and bilateral inguinal and para-aortic lymph nodes metastasis. Histopathological examination of percutaneous biopsy specimens was performed. The diagnosis was stage IV (cT4N1M1) epidermal SCC, which was treated with palliative external radiation therapy. Conclusion The SCC in this case was thought to arise from mechanical stimulus of the suprapubic cystostomy. Physicians and patients should pay careful attention to any signs of neoplasms with long-term indwelling catheters, such as skin changes around the suprapubic cystostomy site. This case presentation is only the fourth report of SCC arising from the suprapubic cystostomy tract in the literature. In cases of unresectable tumors and contraindications to chemotherapy, palliative radiotherapy may lead to disease remission and symptom relief.
