Abstract Background: Metastasis to the urinary bladder from gastric cancer is rare. Metastasis to a diverticulum of the bladder from gastric cancer is extremely rare. We report a case of isolated bladder metastasis from gastric cancer and invasion localized to the muscularis propria of the primary site (stomach). Case presentation: A 90-year-old female presented with nausea and vomiting that was diagnosed as gastric cancer, the patient also had intermittent hematuria. Pelvic computed tomography identified an abnormally thickened area in the bladder wall that was diagnosed as a diverticulum of the bladder. A biopsy of the bladder wall revealed well differentiated tubular adenocarcinoma metastatic from gastric carcinoma. Conclusion: Almost all cases of bladder metastasis from gastric cancer had peritoneal dissemination. This particular presentation of bladder metastasis from gastric cancer, to the best of our knowledge, has not been previously reported.
Background
Case presentation
Metastasis to a diverticulum of the bladder from gastric cancer is extremely rare [1]. Gastric cancer has a tendency to metastasize widely, most commonly to the liver, lung, lymph nodes, bone and peritoneum [2]. The bladder may be involved in the late stages from metastasis and is usually associated with metastasis to other organs [3], but isolated bladder metastasis and invasion localized in the muscularis propria of the primary site (stomach) is extremely rare.
A-90-year-old female presented in November 2003 with a history of nausea, vomiting and dysphagia, with hematuria. On admission her abdomen was slightly distended, tympanic, and slightly tender in the upper abdominal regions, with normal bowe
