Skin metastases from transitional cell bladder cancer.

Three cases of transitional cell bladder cancer metastatic to skin are described. This manifestation of transitional cell uroepithelial malignancy was previously believed to be quite uncommon. The authors' experience suggests that this occurrence is not that rare and that it may reflect increased longevity in successfully treated patients, allowing previously unusual manifestations of metastatic disease to become evident. The role of aspiration skin biopsy is discussed.
