Urachal signet ring cell carcinoma.
Urachal adenocarcinoma is a rare neoplasm associated with poor prognosis. We report a case of urachal signet ring cell carcinoma in a 65-year-old man. He was admitted with a chief complaint of microscopic hematuria. Cystoscopic examination and transurethral biopsy showed an urachal tumor. After undergoing radical cystectomy and intravenous chemotherapy, the patient developed bilateral hydronephroses as a result of bilateral ureteral metastases and bowel obstraction because of the Para-aortic lymphnode metastasis. He has been alive for 5 years after three courses of chemotherapy and a bypass operation.
