Carcinoma of the bladder is a worldwide disease with several histological patterns, 0.5 to 2.0% of which are caused by adenocarcinomas. The etiology of adenocarcinoma of the bladder is unknown. Adenocarcinoma of the bladder may be classified as
primary,
urachal or metastatic based on the site of tumor origin. The primary site of metastatic adenocarcinoma include the rectum, stomach, endometrium, breast, prostate and ovary. Metastasis to the bladder from adenocarcinoma is a relatively rare
phenomenon
occurring in only 0.26% of of cases. When urologic symptoms newly developed to the patients who had malignancy of digestive organs, metastatic malignancy of urinary tract should be considered. Herein, we report a case of metastatic bladder tumor
from
gastric cancer which occurred 15 months after subtotal gastrectomy.
