title: Endodermal sinus tumour associated with benign teratoma of the common bile duct.
abstract: We report a 5-year-old boy with endodermal sinus tumour associated with benign cystic teratoma of the common bile duct (CBD). To our knowledge, there has been one case of teratoma of the CBD in the English literature with no morphological or radiological description. Our case presented a lobulated polypoid mass obstructing the distal CBD on sonography and computed tomography, which resembled the botryoid masses of rhabdomyosarcoma.
