Ureteral fibroepithelial polyp redirects here.

General

  • Presentation may include: hematuria, flank pain, urinary frequency.[2]

Gross

  • Classically proximal ureter.[3]

Microscopic

Features:[2]

  • Polypoid lesion (epithelium on three sides in plane-of-section) covered unremarkable urothelium.

Sign out

A. Right Ureter, Lesion, Resection:
	- Benign urothelial fibroepithelial polyp with focal hemosiderin.
	- NEGATIVE for malignancy.

Micro

The sections shows a polypoid lesion covered by a thin urothelium. The urothelium has an unremarkable appearance; all of the following are absent: anisonucleosis, apparent proliferation, lack of maturation. The core of the lesion is fibrous and edematous. Hemosiderin and siderophages are present.
