TORRES GOMEZ, Francisco Javier; RIVERA HUETO, Francisco Javier  y  TORRES OLIVERA, Francisco Javier. Lymphoepithelioma-like undifferentiated carcinoma of the bladder: Case report. Arch. Esp. Urol. [online]. 2007, vol.60, n.2, pp.192-195. ISSN 0004-0614.

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.

Palabras clave : Bladder carcinoma; Lymphoepithelioma.
