Primary bladder tumor is a frequent urological malignancy, whereas the incidence of metastatic bladder tumor from a distant organ is quite rare. Metastatic bladder tumors are responsible for less than 2 % of all bladder tumors and originate most commonly from a melanoma, breast cancer, and gastric cancer. Signet ring cell cancer is a rare type of bladder malignancy, accounting for approximately 0,24% of all urinary bladder malignancy. We report a case of a 68 years-old woman who underwent total gastrectomy and left pneumonectomy 2 years ago. On routine control, thickening of bladder wall with bilateral grade 1-2 hydronephrosis was detected on ultrasonography and computerized tomography scan.

A bladder tumor was detected and resected with transuretral resection. The histopathological examination revealed secondary Signet ring cell adenocarcinoma of the urinary bladder.
