Benign fibroepithelial polyp of the ureter: A case report

Abstract

Fibroepithelial polyp of the ureter is the most common form of rare benign mesodermal tumors of urinary tract. The etiology of this tumor is still unknown. Hematuria is the most frequent of revealing signs. Imaging methods are not always contributive. The diagnosis is confirmed by histological examination. The treatment of fibro epithelial polyp of the ureter is endoscopic. Case report A 37 year-old patient, without medical or surgical history, presented with a total intermittent hematuria of 3 months duration. Clinical examination was normal. Biology was also normal. Uro CT scan showed an obstructive intra-luminal lesion of 5 cm, localized in left pelvic and iliac regions. In delayed phase, we found a contrast-enhancing lacuna with large implantation base (Fig. 1). Endoscopic exploration showed a 7 cm-sized sessile ureteral polyp, 3 cm far from the ureteral meatus. Its implantation base was at the right iliac ureter. Histological examination concluded to fibro epithelial polyp of the ureter. The patient underwent an endoscopic excision of the polyp. Final histological examination confirmed the diagnosis of fibro epithelial polyp (Fig. 2). After a 4 years follow up, there were no signs in uro CT scan of complications or recurrence (Fig. 3). Open in a separate window Fig. 1 Contrast-enhanced abdominal computed tomography showed a 5 cm intra-luminal ureteral lesion that is obstructive with homogenous contrast enhancement.
