Solitary fibrous tumor of the bladder: Diagnostic challenges and surgical management in an elderly male, a case report and literature review.

INTRODUCTION

Solitary fibrous tumors (SFTs) of the bladder are rare mesenchymal neoplasms that mimic other bladder tumors, requiring a multidisciplinary approach for diagnosis and management.

CASE PRESENTATION

An 81-year-old male with a 30-pack-year smoking history presented with clotting hematuria and acute renal failure. Imaging revealed a large bladder mass causing bilateral ureteral obstruction. Transurethral resection and immunohistochemical analysis confirmed an SFT. The patient underwent cystoprostatectomy with Bricker diversion, achieving full recovery.

DISCUSSION

Bladder SFTs are often misdiagnosed as other spindle cell tumors. Histopathology and CD34 immunopositivity are key for diagnosis. Although typically benign, recurrence and metastasis require long-term follow-up.

CONCLUSION

This case underscores the rarity of bladder SFTs and highlights the importance of accurate diagnosis and complete surgical excision for optimal outcomes.
