ABSTRACT

Urothelial carcinomas are the most common tumor types in urinary bladder; however, there may exist different differentiations in 10-20% of bladder cancer, one of which is urothelial carcinoma that has sarcomatoid- and/or lymphoepithelioma-like differentiation. It is usually seen in males in older age and diagnosed during later stages. They are aggressive malignancies and have low survival. Although there are various treatment models determined in the literature, no certain standard is identified. In this study, we report a case of sarcomatoid- and lymphoepithelioma-like differentiated urothelial carcinoma of the urinary bladder that was treated by partial cystectomy and its results in light of the literature.
