[A glandular-type inverted papilloma of the bladder: apropos a case with an evident chronic irritative factor].
OBJECTIVE
Inverted papilloma of the bladder is a rare condition that presents in the middle-aged. Its histological features and prognosis are unique and its diagnosis is always by anatomopathology. To date, its histogenesis has not been elucidated. The present study reports an additional case of this uncommon disease entity, which is even more so due to its glandular anatomopathological morphology.


METHODS
A case of inverted papilloma of the bladder in a 52-year-old man with a permanent bladder catheter is described. The tumor was located in the posterosuperior bladder wall and had been successfully resected.


RESULTS
The histological diagnosis was that of glandular inverted papilloma of the bladder. The patient is asymptomatic at two years follow up.


CONCLUSIONS
In our view, inverted papilloma of the bladder results from a previous metaplasia in which the chronic irritative factor plays an important role.
