[A case of signet ring cell carcinoma of the urinary bladder].
A 67-year-old man was admitted for complaint of gross hematuria on April 9, 1986. Cytoscopic examination was revealed broad-base tumor, its size was thumb's head, at the right lateral wall of the bladder. Ultrasonography and computed tomographic scan of the bladder demonstrated no evidence of invasion to adjacent organs. The biopsy showed signet-ring cell carcinoma. Radiography of the digestive organs showed no abnormality. A partial cystectomy was performed. Histologically the tumor was limited up to submucosa, that is pT1b. The localization of carcinoembryonic antigen (CEA) on tissue of our case, using the peroxidase-antiperoxidase (PAP) method, was evidenced.
