Fibroépithélial Polyps of the Ureter

“…Some reports on ure teral tumors are quite equivocal on the benign or poten tially malignant nature of the described neoplasm [2,5,8], The second group concerns mesenchymal neoplasms, [12], Fibroépithélial pol yps cannot be classified into either category since they are not tumors, but are to be considered as hyperplasias of the mucosal connective tissue [5].
