Orbital metastasis of urinary bladder carcinoma: a clinicopathologic report and review of the literature.

A 53-year-old male presented with a progressive mass of the left orbit. His medical history included an invasive carcinoma of the bladder diagnosed three weeks earlier. An orbital biopsy was performed and the diagnosis was that of an orbital metastasis of urinary bladder carcinoma. The patient developed widespread metastatic disease and unfortunately died one month after the diagnosis of orbital metastasis. Orbital metastasis of urinary bladder carcinoma is associated with a poor prognosis and is more frequently observed in older people. In addition, it is five times more prevalent in men than in women.
