[Primary signet ring cell carcinoma of the urinary bladder: a case report]
Abstract:
Gross hematuria and urinary frequency caused a 71-year-old man to visit our hospital. A non-papillary tumor was identified on the posterior wall of the urinary bladder and the pathological diagnosis was signet ring cell carcinoma. Upper gastrointestinal endoscopy, computed tomographic scanning, barium enema revealed no involvement of other organs. Radical cystectomy and creation of an ileal conduit were performed. The histopathological stage was pT4N1M0. Apart from subacute ileus, the postoperative course was uneventful. Signet ring cell carcinoma of the bladder is a rare entity and we have identified 41 cases in the Japanese literature. This tumor usually has a poor prognosis. Our patient is currently free from disease at 5 months after the surgery.
