title: [A case of urachal carcinoma associated with elevated levels of CA19-9].
abstract: A 53-year-old man was admitted with the chief complaint of gross hematuria. Cystoscopic examination revealed a non-papillary tumor at the dome of the bladder. The plasma level of CA19-9 was markedly elevated before treatment. Total cystectomy with en bloc removal of the tumor and radical lymphadenectomy were performed under the diagnosis of urachal carcinoma. The plasma CA19-9 level decreased to the normal level after operation and was well correlated with postoperative course. The monitoring of CA19-9 may be useful for follow up in patients showing a high elevation of CA19-9.
