title: [Carcinoma of the urachus with variable pathological findings: report of a case and review of literature].
abstract: A 71-year-old man was admitted with the chief complaint of gross hematuria. Cystoscopic examination showed a broadbased papillary tumor at the apex of the bladder. There was edema of the mucous membrane around the tumor. CT-scan demonstrated a mass extending from the bladder dome superiorly. Partial resection of the bladder was done. Pathological examination revealed grade 3 transitional cell carcinoma, with scattered adenocarcinoma and squamous cell carcinoma foci. Chemotherapy with bleomycin (BLM) and cis-dichlorodiamine platinum (CDDP) was done postoperatively. Ten months after the operation, he was readmitted because of recurrence in retroperitoneal lymph nodes. Chemotherapy with BLM and CDDP was done, but he died of pulmonary complications. Autopsy revealed retroperitoneal lymph node metastasis of transitional cell carcinoma. There was no metastasis to any other organ. We briefly discuss 275 cases of the carcinoma of the urachus collected from the Japanese literature.
