title: Metastatic sacrococcygeal yolk sac tumor: A misleading diagnosis.
abstract: Sacrococcygeal yolk sac tumor (YST) is an extremely rare malignant extra-gonadal germ-cell tumor, which usually succeeds to the degeneration of more common benign teratoma. We describe here an unprecedented case of conus medullaris compression by a spinal metastasis from a pure sacrococcygeal YST in a 1½ years old girl, which was misdiagnosed initially as an anal fissure and stress the need of a meticulous clinical examination and further screening in young patients presenting with sphincter disturbances.
