A Rare Case of Metastatic Urachal Carcinoma
Urachal carcinoma is a rare tumor, it represents about 0.5-1% of all bladder malignancies. In the majority of cases it is an adenocarcinoma. For the treatment it is recommended for resectable tumors, a partial cystectomy with resection of the urachal ligament, the bladder dome and umbilicus. There is no standard neoadjuvant or adjuvant treatment, and the combinations of 5-fluoruracil with cisplatin are active in metastatic stage. A higher risk of relapse after surgery has been observed in some situations: positive margins, lymph node involvement, involvement of the peritoneal surface, or in the case of the umbilicus was not resected en-bloc.
