Sarcomatoid carcinoma of the urinary bladder and concomitant abdominal aortic aneurysm: a case report and literature review

We report the diagnostic evaluation, management, and intermediate-term outcomes of a rare variant of bladder cancer and concomitant Abdominal Aortic Aneurysm. A 62 year old male with gross haematuria and Abdominal Aortic Aneurysm was admitted to our hospital. Cystoscopy revealed a large bulky mass occupying the posterior bladder wall. The tumor was transurethrally resected and its histology showed a Sarcomatoid Carcinoma of the urinary bladder. Due to the aggressive behavior of the tumor and the risk of aneurysm rupture, concomitant endovascular exclusion of Aneurysm, total cystectomy with urinary diversion was performed. 12 months after radical surgery the patient was alive without any local recurrence, distant metastasis, and thrombosis of iliac axis. To our knowledge this study is the first report to describe data on the diagnostic evaluation, Management, and intermediate-term outcomes in Sarcomatoid carcinoma and Concomitant Abdominal Aortic Aneurysm. Multi-institutional collaboration is important to perform clinical trials of adequate sample size to design more effective treatments for these aggressive cancers in the presence of Concomitant Abdominal Aortic Aneurysm.
