A 62-year-old male was admitted to our clinic with the complaints of gross-hematuria and miction pain. Cystoscopic examination revealed non-papillary tumor around the orifice of the left ureter and the left wall. Histopathological findings of the biopsy specimen demonstrated signet-ring cell carcinoma, and the specimen was stained positively by the peroxidase-antiperoxidase technique. No malignant findings in any other organs including gastrointestinal tract and prostate were detected. This patient underwent total cystectomy with ileal conduit and histopathological staging was pT3bNOMO. He was followed with no evidence of local recurrence or metastasis for 29 months after operation. The 45 reported cases with primary signet-ring cell carcinoma of the urinary bladder including our case are reviewed and some characteristics of this entry are discussed.
