title: Bladder metastasis from maxillary sinus undifferentiated carcinoma: a rare case.
abstract: We report the rare case of a 72-year-old woman with maxillary sinus undifferentiated carcinoma with metachronous metastasis localized to the bladder. Bladder metastases and maxillary sinus carcinoma are rare tumors. The bladder is not 1 of the usual sites of distant extension for parasinus tumors. To our knowledge, no data have been reported regarding bladder metastasis originating from a maxillary sinus carcinoma.
