title: Extravesical tumor implantation caused by perforation during transurethral resection of a bladder tumor: a case report.
abstract: We report a case of invasive bladder cancer in which cancer dissemination occurred through a perforation of the vesical wall during transurethral resection of the tumor. A radical cystectomy was performed 1 month later and several clusters of viable cancer cells were histologically identified in a fibrous foreign body granuloma in the paravesicular adipose tissue of the lymphadenectomy specimen. The patient received adjuvant chemotherapy, but developed right inguinal lymph node metastasis 21 months after cystectomy.
