OBJECTIVE: To present a new case of a primary lymphoepithelioma-like carcinoma of the urinary bladder. MATERIAL AND METHODS: We describe the clinical, diagnosis, treatment and development of this kind of tumor. Review of the literature. CONCLUSIONS: It is an unusual type of bladder cancer that requires a carefully analyse from the pathologist and a confirmation by means of immunohistochemistry techniques. The focal form is associated with poor prognosis. Radical cystectomy is the gold standard. This kind of tumor has sensibility to chemo and radiotherapy, who can be used as adjuvant therapy.
