Solitary fibrous tumor of the bladder: A rare cause of bladder outlet obstruction in an adult male.

INTRODUCTION

Solitary fibrous bladder tumors are extremely uncommon, with only a few cases reported. These fibroblastic mesenchymal neoplasms are typically benign, indolent, and slow growing.

CASE PRESENTATION

A 44-year-old male patient with obstructive uropathy was referred to our unit for workup. Ultrasonography and MRI of the pelvis showed a large, well-circumscribed bladder mass, also visualized cystoscopically. This mass was excised en bloc using the Pfannenstiel approach. Histopathological and immunohistochemical analyses revealed a solitary fibrous tumor.

CONCLUSION

The management of SFTs can be challenging due to the lack of established guidelines. Hence, we offered our patient long-term follow-up. Twelve months postoperatively, no recurrence or metastases were found on the follow-up imaging.
