“…They most commonly present as a single, small polyp. Reports of multiple, bilateral polyps are extremely rare, whereas the mean diameter of UFPs was reported to be <5 cm; larger polyps may extend into the bladder cavity and may be difficult to distinguish from bladder tumors ( 4 , 5 ). In the majority of the cases, the upper ureter is the most common site of origin of these tumors, whereas polyps derived from the lower urinary tract are not as frequent ( 6 ).…”

Primary ureteral fibroepithelial polyps (UFPs) are rare benign tumors of mesodermal origin. The majority UFPs are observed in the proximal part of the ureter and most commonly on the left side. The mean diameter of UFP is reported to be <5 cm. We herein present a rare case of a long primary ureteral polyp originating from the lower ureter in a 53-year-old woman. Following computed tomography, magnetic resonance imaging, retrograde pyelography and ureteroscopic examination, a preliminary diagnosis of giant primary lower ureteral polyp protruding into the bladder was obtained. Polyp resection and resection of the narrow ureteral segment with a V-shaped end-to-end anastomosis were performed. The length of this polyp was 15.0 cm, and the final pathological diagnosis was UFP. No recurrence or ureteral stenosis were observed at the 12-month follow-up. A supplementary review of previously published cases and related literature is also included.

“…The aetiology of these fibroepithelial polyps is unclear; however, it is speculated that chronic persistent irritation due to renal stones, infection, obstruction, trauma and developmental defects may be the causative factors 11. As far as our case is concerned, there were no definite aetiological factors.…”

“…Imaging and cystoscopy showed a mass originating at the middle third of the ureter and protruding into the bladder. The polyp was excised and ureteral end-to-end anastomosis was done 11. As far as our case is concerned, the polyp involved the whole length of the ureter, reaching up to the renal pelvis and it was impossible to separate the polyp from the ureteric wall.…”

Giant fibroepithelial polyp of the ureter

et al. 2017

Giant fibroepithelial polyp is a rare cause of ureteric/ureteropelvic junction (UPJ) obstruction. We report a rare case of giant fibroepithelial polyp in a 32-year-old woman involving the whole length of the ureter, reaching up to the UPJ which was clinically and radiologically considered to be urothelial carcinoma. Frozen section showed a polypoid lesion lined by urothelium with no evidence of dysplasia or malignancy. Subsequently, nephroureterectomy was done as there was marked renal hydronephrosis and it was impossible to separate the polyp from the wall of the ureter. Histopathological examination and immunohistochemistry confirmed the diagnosis of giant fibroepithelial polyp, ruling out malignancy.

Introduction: Polyp of breast nipple is a rare benign tumor which is pedunculated. The typical polypoid appearance makes the clinical diagnosis apparent. The breast nipple polyp in woman are generally small in size. Giant size fibroepithelial polyp are very rare. Case Report: This is case report of a large size fibroepithelial polyp arising from nipple of left breast in 40-year-old woman. This polyp was more than 10 cm size in length having a long pedicle. This polyp with its pedicle was excised from nipple. The histopathological diagnosis was consistent with fibroepithelial polyp. Conclusion: The large size fibroepithelial polyp of nipple breast is very rare.
