Benign phyllodes tumor of the distal end of the ureter: an extremely rare case and literature review.

A phyllodes tumor (PT) is a biphasic fibroepithelial lesion that is most commonly found in breast tissue, whereas it is uncommon in ureter tissue. Only one case has been documented so far. There are some similarities in histology and clinical characteristics between this type of tumor and PT of the female breast: the lesions can be surgically removed, but some recur locally and invade directly into the breast. This case of a primary PT of the ureter is useful for pathologists and clinicians.
