Metastatic squamous cell carcinoma of the paranasal sinuses from a primary squamous cell carcinoma of the urinary bladder.
Metastatic tumours of the paranasal sinuses from primary lesions of the urogenital tract are rare, with about 50 cases so far being reported in the literature. The most frequent primary lesions is a renal carcinoma. We have experienced a case of paranasal sinus malignancy. There were no symptoms of urinary tract carcinoma preceding those in the paranasal sinuses. This case was later revealed at autopsy to be a metastasis from a diverticulum of the urinary bladder.
