Skin involvement from micropapillary bladder carcinoma as the first clinical manifestation of metastatic disease

Cutaneous metastases from transitional cell carcinoma (TCC) of the bladder occur infrequently. We report the case of a 68-year-old man presenting with an isolated skin nodule a few weeks after local excision of a micropapillary bladder carcinoma. This rare variant of TCC, which is strikingly reminiscent of the histological pattern of ovarian papillary serous carcinoma, is associated with poor prognosis and apparently high metastatic potential.
