Abstract;Although umbilicus originated malignant tumor is a rare entity, it is one of the most important entities for differential diagnosis among pediatric mass-forming umbilical disorders such as retained urachal and vitelline duct anomalies. The authors present two cases of urachal malignant tumor. The first patient was a 15-month-old girl with urachal rhabdomyosarcoma, who underwent emergency surgery for tumor rupture and received postoperative chemotherapy. The second patient was an 18-month-old girl with urachal leiomyosarcoma. Her tumor was resected after reduction with preoperative chemotherapy. Both patients survived and have been healthy without recurrence during the follow-up period. (author abst.)
