[Distal bone metastases of transitional-cell carcinoma of the bladder. Apropos of a case].
OBJECTIVE
To report a case of transitional cell carcinoma of the bladder metastatic to the right knee and review the literature.


RESULTS
A 65-year-old patient who had refused to undergo surgery for a T2 N0 M0 bladder tumor in 1995 was admitted for poor general condition and a mass in the right knee. Biopsy confirmed bony metastasis of a carcinoma compatible with primary urothelial tumor of the bladder.


CONCLUSIONS
Bony metastasis of transitional cell carcinoma of the bladder is relatively frequent and mainly to the spine. Distal bony lesions are rare and usually appear in the advanced stages of the disease.
