title: [Metastatic bladder tumor disseminated lymphogenously from gastric cancer: a case report].
abstract: A 59-year-old man was referred to our clinic with a complaint of frequent urination, voiding pain, and macroscopic hematuria. He had undergone total gastrectomy for mucinous adenocarcinoma, 21 months earlier. Pelvic computed tomography revealed a thick bladder wall all around. There were no other metastatic sites except for paraaortic lymph nodes. Transurethral resection of the bladder tumor was performed. The specimen showed signet ring cell carcinoma and revealed the same pathological findings as the primary gastric cancer. We diagnosed him with metastastic bladder tumor lymphogenously disseminated from gastric cancer. Such lymphogenous metastases from gastric cancer at the entire bladder wall without other apparent lesions have rarely been reported in the Japanese literature.
