title: Squamous cell carcinoma of bladder diverticulum with initial symptoms produced by metastasis to maxillary sinus.
abstract: A rare case of squamous cell carcinoma in the bladder diverticula of a 74-year-old man with initial clinical symptoms caused by metastasis to the maxillary sinus is reported. The histopathological examination at autopsy confirmed the metastatic squamous cell carcinoma in the maxillary sinus from the bladder diverticula. The vertebral vein plexus seems responsible for this type of metastasis.
