Introduction:
Lymphoepitheliomas are malignant epithelial tumors of the nasopharynx characterized by an important lymphoid proliferation at histological examination. Lymphoepithelioma-like carcinoma is a rare tumor of the bladder for which the therapeutic strategy is not clearly defined.
Case Presentation:
We report the case of a 64-year-old Moroccan man who presented with macroscopic hematuria. Investigations revealed a muscle-invasive lymphoepithelioma-like carcinoma of the bladder. Therefore he underwent a radical cystoprostatectomy with a good outcome.
Conclusion:
This case illustrates pathogenic, clinical and therapeutic features of this unusual tumor.
