title: Transitional cell carcinoma of the urinary bladder metastatic to the oral mucosa.
abstract: Metastatic tumors in the oral cavity are rare and usually affect the jaws more often than the oral soft tissues. In particular, metastases confined to the oral mucosa are extremely rare and originate mainly from the lung and breast. Only one case restricted to the oral mucosa and originating from urinary bladder carcinoma has previously been described. We report on a painful polypoid mass located in the oral mucosa with no bone involvement that was confirmed to be a metastatic oral tumor that originated from transitional cell carcinoma of the urinary bladder and progressed rapidly.
