Urothelial Carcinoma - Rhabdoid Variant

Comments:
Urothelial carcinomas with rhabdoid morphology have been described. This tumor is composed of sheets of large, discohesive cells with vesicular nuclei, prominent nucleoli and abundant eosinophilic cytoplasm. It was admixed with areas of conventional high-grade urothelial carcicnoma. When the tumors have pure rhabdoid morphology, one has to exclude malignant extrarenal rhabdoid tumor.
