Sarcomatoid Urothelial Carcinoma of the Urinary Bladder With Chondrosarcomatous and Concurrent Divergent Squamous Cell Carcinoma Differentiation– A Rare Entity

We present an extremely rare case where the sarcomatoid urothelial carcinoma of the urinary bladder was present with chondrosarcomatous and squamous cell differentiation. A 74-year-old male smoker presented with intermittent hematuria with the passage of clots. On imaging, an irregular polypoidal le...

Sumario:We present an extremely rare case where the sarcomatoid urothelial carcinoma of the urinary bladder was present with chondrosarcomatous and squamous cell differentiation. A 74-year-old male smoker presented with intermittent hematuria with the passage of clots. On imaging, an irregular polypoidal lesion was diagnosed near the right vesicoureteric junction, and transurethral resection of the bladder tumor was performed. Histopathological examination showed sarcomatoid urothelial carcinoma with chondrosarcoma and squamous cell differentiation. He refused the surgical treatment of radical cystectomy and underwent Gemcitabine and Cisplatin chemotherapy. He died nine months after the diagnosis. Sarcomatoid urothelial carcinoma is a high-grade biphasic neoplasm with malignant epithelial and mesenchymal components. Its association with squamous cell carcinoma is infrequent. It is very aggressive, and there is no standard treatment for this disease. The radical surgical option appears to be the main form of treatment. It is scarce with a grave prognosis.
