A 24-yr-old woman presented with gross haematuria and a huge tumour of the right bladder wall. At transurethral resection, a solid tumour was seen covered with normal mucosa. The pathological evaluation revealed a solitary fibrous tumour (SFT) of the urinary bladder. For final treatment, a partial cystectomy was performed; tumour-free margins were ensured by frozen-section analysis. This is the first case in the literature presenting intravesically in a young woman. Due to the difficulty in discriminating between malignant and benign growth pattern of this tumour entity, a regular follow-up after conservative treatment is mandatory.

[Show abstract][Hide abstract]ABSTRACT: The clinical and radical prostatectomy features of a case of solitary fibrous tumour (SFT) of the prostate identified on needle biopsy are presented. The main differential diagnoses are discussed. SFTs involving the prostate are relatively uncommon, with only isolated cases reported in the literature. Owing to their relative rarity and lack of long-term follow-up, the clinical behaviour of prostatic SFTs is difficult to predict. Complete resection of the tumour is currently the single main prognostic factor.
[Show abstract][Hide abstract]ABSTRACT: Spindle cell lesions of the urinary tract encompass a variety of benign and malignant tumours as well as a group of lesions of controversial nomenclature that is the subject of ongoing debate. This review focuses on our current and evolving understanding of the lesion variably referred to as inflammatory myofibroblastic tumour, pseudosarcomatous myofibroblastic proliferation or inflammatory pseudotumour and the main differential diagnoses of sarcomatoid carcinoma and sarcoma. Other spindle cell lesions of the bladder are described.
[Show abstract][Hide abstract]ABSTRACT: Solitary fibrous tumor (SFT) in bladder is extremely rare. In this study, we reported one case of bladder SFT and reviewed the only ten cases of the disease that had been reported so far. The patient suffered from residual urine sensation and urethral pain. Cystoscopy revealed a 7-cm protruding mass at the dome of the bladder, and bladder mucosa biopsy showed normal differentiation of the bladder mucosa with a small amount of inflammatory cells. Radical resection of the tumor was performed in this patient. Pathological examination found uniform, haphazardly arranged spindle cells, the majority of which were CD34-positive and Vimentin-positive and proved that the mass was a solitary fibrous tumor. Within a period of 9 months of follow-up, no reoccurrence was found.
