Abstract
Background: Solitary fibrous tumors (SFTs) of the urinary bladder are rare mesenchymal tumorswith occasional malignant potential. Owing to the rare nature of the disease, diagnostic and surgical management strategies remains variable. The gold standard treatment is complete surgical excision with negative margins, while recurrence and metastasis of aggressive variants during the follow-up can be managed by surgical excision and radiotherapy.
Case presentation: Here, wepresent a very rare case of dual malignancy, SFT of the urinary bladder and adenocarcinoma of the prostate, managed by radical cystoprostatectomy and bilateral extended pelvic lymph node dissection in an elderly male presenting with mixed LUTS(lowerurinary tract symptoms). The diagnosis of SFT was confirmed by immunohistochemical marker-STAT6 positivity. Postoperatively, after six monthsof follow-up, there was no evidence of disease recurrence.
Conclusion: Complete surgical resection with negative margins via open, laparoscopic or robotic surgery is the operation of choice.
