Abstract

The solitary fibrous tumor is an infrequent neoplasm of mesenchymal origin, mainly pleural, exceptionally urogenital.

Our patient is 71 years old with no specific history who was presented to the emergency room for acute retention of urine relieved by a bladder catheter. An Uroscanner showed a thickening of the bladder wall which prompted the medical staff to perform a RTUV whose histological and immunohistochemical study confirmed the diagnosis of a solitary fibrous tumor of the bladder.

Solitary fibrous tumors remain slow-growing neoplasms regardless of their site. The prognosis and aggressiveness are difficult to specify. Recurrences, locoregional extension and distant metastases can be seen in 10 to 20% of cases.

Introduction

Solitary fibrous tumor is a rare tumor of mesenchymal origin affecting mainly adults without sex preference, initially and long described in the serous membranes, especially the pleura. More recently, it has been described in organs and multiple tissues. The location in the urinary tract remains exceptional with a few cases described in the bladder and prostate. The diagnosis is purely histological confirmed by the immunohistochemical study.

Case Presentation

We report the case of a 71-year-old man with no medicalsurgical history who was presented to the emergency room for acute retention of urine relieved by bladder catheterization. The patient was hospitalized in the urology department, where examination revealed the presence of urinary symptoms such as dysuria and pollakiuria dating back two months.

The clinical examination found a patient in good general condition, well oriented in time and space, the digital rectal examination found a flexible prostate with an estimated volume of 60 grams. The ganglionic areas are free. The remainder of the physical examination is unremarkable.

The biological assessment reports normal renal function and a PSA of 4 ng/ml. The cytobacteriological examination of the urine is sterile.

An abdominal ultrasound was performed which showed a prostate weighing about 80 grams. Uro-CT showed a thickened-walled bladder of heterogeneous contents (Figure 1). UVR (transurethral bladder resection) was performed and referred to the pathological anatomy department.
