BackgroundPatients 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 presentationA 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.ConclusionThe 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.

Wound necrosis and groin lymphorrhea after inguinal lymph nodes dissection are serious complications. But treatment options for these complications are somewhat controversial. We report a patient who underwent an inguinal lymph node dissection for a regional metastasized squamous cell carcinoma of penis. Unfortunately, a extensive wound necrosis occurred with lymphorrhea (300 cc daily). After operative debridement, negative pressure wound therapy was started. We had used the instrument "V.A.C. (Vacuum Assisted Closure) ATS Therapy System" (KCI U.S.A.). After 11 days of negative pressure wound therapy, the good formation granulation tissue was observed and the lymphatic leakage was prominently decreased. This therapy was performed without serious complications but tolerable localized pain due to negative pressure. There were only seven reports that gave the description of an approach using negative pressure wound therapy for the less invasive treatment of lymphocutaneous fistulas and evaluated the efficacy of this therapy as an alternative medical procedure for treating lymphorrhea. This case suggested that negative pressure wound therapy could not only promote wound healing but also improve intractable lymphorrhea.
