Signet-Ring Cell Gastric Carcinoma Metastatic to Bladder

Bladder Signet-Ring Cell Carcinoma (SRCC) is extremely rare. It is most often primary, but metastatic disease is described in a few cases in literature. Herein we describe a case of primary SRCC of the stomach with metastasis to the bladder that did not have the chance to receive treatment and passed away due to tumor aggressiveness. We also reviewed the literature and discussed the etiology, prognosis and treatment of bladder SRCC.
