[Case report: lymph node metastasis of micropapillary bladder tumor that completely responded to radiation therapy]

A 67-year-old woman was referred to our hospital in April 2003 because of a bladder tumor. Cystoscopy revealed a thumb tip size and wide based papillary tumor. TUR-Bt was performed. Histologically, the tumor was UC, G3 and pT1. There was no recurrence of tumor in bladder after that. 3 years later, she was referred again with high serum levels of CA19-9 and CEA. Computed tomography showed bilateral lymph node swelling in the pelvis. An open biopsy of the lymph node was done and it contained UC with a micropapillary component. Radiation therapy achieved completely response. Serum levels of CA19-9 and CEA were within normal limits. She has never had a recurrence of tumor until July 2007.
