Sarcomatoid urothelial carcinoma is a rare aggressive malignant neoplasm of the urinary bladder. It usually presents at an advanced stage and thus carries a poor prognosis. These tumours are usually managed with multimodal therapies such as cystectomy and chemotherapy. In the present case, a 72-year-old man presented with gross haematuria and was diagnosed as sarcomatoid urothelial carcinoma with chondrosarcomatous differentiation and extensive stromal osseous metaplasia. The patient was managed with transurethral resection of bladder tumour (TURBT), followed by intravesical chemotherapy. The patient is doing well post 14 months follow-up. Hence, complete TURBT with chemotherapy is also a viable option for patients who prefer to preserve bladder.
