[Urothelial inverse papilloma. Review of the literature (appropos of 2 cases: 1 vesical, the other urethral)].
The authors report two cases of urothelial inverse papilloma and review the 94 observations in the published literature. Some fundamental features of the condition are outlined: 1) DEFINITION: paramalpighian papillary tumor which spreads towards the chorium but does not invade it, and lies under the intact urothelium which is folded towards the lumen of the urinary tract, 2) Site: usually cervicotrigonal but may be urethral; 3) Evolution: usually benign but sometimes recurrent; 4) Histogenesis: abnormal proliferation of Von Brunn's islets. 5) Association: possible with bladder carcinomas.
