[Lymphoepithelioma-like undifferentiated carcinoma of the bladder. Case report].
OBJECTIVE
High-grade lymphoepithelioma-like urothelial carcinoma is a rare neoplasia in the bladder, and its relationship with Epstein-Barr virus has not been demonstrated.


METHODS
We report the case of an old male presenting with recurrent hematuria diagnosed of this tumor.


RESULTS
These are neoplasias with a great lymphocyte component, sometimes predominant, which may lead to histological confusion with inflammatory processes like chronic cystitis or even lymphomas.


CONCLUSIONS
Despite their infiltrative character and high cytological and architectural grade their prognosis is better than urothelial carcinomas of the same grade and stage, but this only applies for pure forms and those with predominant lymphoepithelioma-like pattern.
