Retroperitoneal fetiform teratoma in an infant

Fetus in fetu is a rare intra-abdominal mass secondary to abnormal embryogenesis in a diamniotic monochorionic pregnancy. Teratoma, unlike fetus in fetu, does not show the vertebral axis or regional distribution of the organs. We report a 9-month-old male infant who presented with a large abdominal...

Description
Summary:Fetus in fetu is a rare intra-abdominal mass secondary to abnormal embryogenesis in a diamniotic monochorionic pregnancy. Teratoma, unlike fetus in fetu, does not show the vertebral axis or regional distribution of the organs. We report a 9-month-old male infant who presented with a large abdominal lump. The retroperitoneal mass was excised. On opening the sac, well-formed fetus-like structure was seen. The mass was connected to a yolk sac-like structure. The mass had the rudimentary head, thorax, abdomen, and finger-like buds giving a fetiform appearance but without vertebral column. Histopathological examination confirmed fetiform teratoma. The outcome was favorable.
