title: An intraocular yolk sac tumor in a child.
abstract: OBJECTIVE
  To report a case of intraocular yolk sac tumor (YST) misdiagnosed as retinoblastoma (RB) by several hospitals.
  
  
  METHODS
  A 2-year-old girl presented to our hospital because of swelling and pain of her left eye for 2 months. The patient underwent an enucleation followed by chemotherapy. Pathologic and immunohistochemical examination of the specimen verified the diagnosis of YST. The patient underwent chemotherapy with the bleomycin, etoposide, and cisplatin regimen. At 1 year follow-up, our patient is in good health status.
  
  
  CONCLUSIONS
  In children, an intraocular tumor without calcification could be YST. Treatment options include enucleation and chemotherapy.
