Abstract

The sarcomatoid variant of urothelial carcinoma (SVUC) is an uncommon histological variant of urothelial carcinoma. Sarcomatoid carcinomas are aggressive malignancies with poor prognosis, which by definition are biphasic neoplasms with both an epithelial and a mesenchymal component. There is no consensus opinion on the best treatment modalities for this tumor. Herein on are reported 5 cases of SVUC with a brief review of the literature. The data was collected from the medical records in the Department of Urology, at the University Hospital Center of Rabat Morocco during the period from January 2014 to December 2017.
