Résumé

We report two cases of a poorly known variant of transitional cell carcinoma, the << nested variant of urothelial carcinoma >>. This tumor is composed of small islands or nests of transitional cells, presenting little atypia and mimicking yon Brunn's nests. This low grade tumoral variant seems to behave as a high grade tumor of the same stage. Deep biopsies are necessary to display tumoral invasion, which allows the diagnosis. Importance of the knowledge of this entity is highlighted in order to avoid misdiagnoses that could delay appropriate therapy.
