Orbital metastases from transitional-cell cancer of the urinary bladder.

Transitional-cell cancer accounts for 90% of the histological types of cancer of the urinary bladder. This tumor most often spreads towards the lymph nodes, lung and bones, but other much more infrequent metastatic sites such as the orbit, have also been described. We report on 2 patients with transitional-cell bladder tumors that developed metastases to the orbit.
