Background: Sarcomatoid carcinoma of the urinary bladder (SCUB) is a rare and aggressive malignancy with limited clinical data due to its infrequency. This case report contributes to the existing knowledge by presenting a patient with SCUB and highlighting the diagnostic workup, treatment course, and clinical outcomes. 

Case presentation: A 57-year-old man presented with lower urinary tract symptoms and hematuria. Imaging revealed a 4 cm bladder tumor. Transurethral resection of bladder tumor (TURBT) confirmed pT2 sarcomatoid carcinoma. Radical cystoprostatectomy with bilateral pelvic lymphadenectomy and urinary diversion was performed. Pathological examination confirmed SCUB with no lymph node involvement. The patient remains disease-free at two years follow-up. 
Conclusion: SCUB is an uncommon malignancy with a poor prognosis. Radical cystectomy is the preferred treatment; however, outcomes remain poor. A multimodal approach may offer improved outcomes for locally advanced diseases. Further research is needed to establish more effective treatment strategies.
