Exploring the Rare Case of a Sarcomatoid Variant of Urothelial Carcinoma

A sarcomatoid variant of urothelial carcinoma (SVUC) is an extremely rare variant, which accounts for only 0.1-0.3% of all urothelial carcinomas of the bladder. SVUC is distinguished by the presence of biphasic components; there can be morphological and/or immunohistochemical substantiation of epithelial and mesenchymal differentiation. The patients with this variant have been associated with very poor disease-specific and overall survival rates in comparison with the high-grade pure urothelial carcinoma. Being a rare entity, it usually presents at a higher grade and is related to a dismal prognosis in comparison with conventional urothelial carcinoma. Careful examination, early diagnosis, and effective treatment are the most important steps for good survival. Here, we report a 58-year-old male who presented with complaints of hematuria for one and a half months with histopathology showing features of SVUC.
