Abstract
Fibroepithelial polyps are extremely rare benign mesodermal tumours in children that
can cause ureteropelvic junction (UPJ) obstruction. We report on a 10-year-old boy
presenting with UPJ obstruction due to a fibroepithelial polyp, and review 28 similar
published paediatric cases.
Les polypes fibro-épithéliaux, cause de l'obstruction de la jonction pyélo-urétérale
chez l'enfant. Report d'un cas et revue de la littérature
Les polypes fibro-épithéliaux sont des tumeurs mésodermiques extrêmement rares chez
l'enfant qui peuvent causer une obstruction de la jonction pyélo-urétérale (UPJ).
Nous rapportons le cas d'un enfant de 10 ans se présentant avec une obstruction de
la jonction pyélo-urétérale, due à un polype fibro-épithélial et revoyons 28 cas publiés
dans la littérature pédiatrique.
