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.
口腔转移性肿瘤罕见,通常累及颌骨的频率高于口腔软组织。特别是局限于口腔黏膜的转移瘤极为罕见,主要起源于肺和乳腺。此前仅报道过一例局限于口腔黏膜且起源于膀胱癌的病例。我们报告了一例位于口腔黏膜的疼痛性息肉样肿物,无骨质受累,经证实为起源于膀胱移行细胞癌且进展迅速的口腔转移性肿瘤。
