Abstract

Although embryonal rhabdomyosarcoma has been frequently reported in genitourinary tract, head and neck, embryonal rhabdomyosarcoma of the biliary tree is an extremely rarte. It must be considered in differential diagnosis of jaundice in childhood. About 35 cases have been reported in world literatures, since first description on 1875, by Moxon and Wilks. We present a case of embryonal rhabdomyosarcoma of the biliary tree in a 25 months old boy with brief review of literatures. Since chief complaints of this case were jaundice and loss of appetite, the first clinical diagnosis was infectious hepatitis. On ultrasound examination, there is a space occupying lesion in right lobe of liver and it was diagnosed as hepatoma. Choledochoduodenostomy with biopsy was done. The operation revealed dilated common bile dut and both hepatic ducts which were filled with light brown jelly like materials and diagnosed as embryonal rhabdomyosarcoma on frozen and permanent senions. In gross and histologic characteristics, this tumor resembles embryonal rhabdomyosarcoma(sarcoma botryoides) in other locations. In spite of chemo-and radiotherapy after operation, the boy was died.
