title: Solitary calcaneal metastasis in superficial bladder carcinoma.
abstract: We report a case of a solitary calcaneal metastasis in a patient with superficial bladder carcinoma. The patient underwent transurethral tumor resection twice because of local recurrence. Both histologic examinations revealed a grade 2 PT1 superficial transitional cell carcinoma of the bladder. The metastasis was detected four months after the initial cystoscopy, due to severe leg pain. The lesion was curetted and filled with bone cement. A year later, a below knee amputation was performed because of local recurrence. This case deserves special attention, for two reasons. First, metastatic carcinoma to the bones of the foot is very rare. Although bony metastasis by transitional cell carcinoma of the bladder can be seen, presenting as a symptomatic solitary lesion after superficial bladder carcinoma is extremely unusual. Second, failure to control bladder tumours by local means might be an indication for an early cystectomy, even in tumours with no evidence of muscle invasion, in order to prevent distant metastasis.
