title: [Bladder transitional cell carcinoma with metastasis to the maxillary sinus as first symptom].
abstract: Maxillary sinus metastasis are very uncommon tumors (fifty have been reported). The most frequent ones are renal adenocarcinoma, breast and lung tumors. Up to now there is only a reported case of bladder carcinoma in maxillary sinus. We report a 67 years old male with a right maxillary tumor two months ago. FNA demonstrated a transitional cell bladder tumor. The treatment was chemotherapy. The patient died two months later. We reported some considerations about metastatic tumors of paranasal sinus.
