[Inverted bladder papillomas. Report of 3 cases and review of the literature].

The authors present three cases of what are currently called inverted, bladder papillomas and make a review of the literature, during the course of which they have found 98 cases published under this name so far. With regard to this name, provided by POTTS and Hirst in 1963 and which has proved so popular in the world literature, this does not mean that the picture was described by them for the first time as many European authors had already done so, from ALBARRAN (1891) to PASCHKIS (1927). Emphasis is placed on the value of following an oncological system in order to prevent diagnostic and therapeutic mistakes and they stress that the suitable treatment for these neoplasias is UTR.
