  • On microscopic histopathological analysis, pineal yolk sac tumor is characterized by poorly differentiated endothelium-like, cuboidal, or columnar cells.
  • Pineal yolk sac tumor is demonstrated by positivity to tumor markers such as AFP, cytokeratin, and AAT.[2]
  • In upto 50% of cases, these tumors co-exist with other germ cell tumors.[3]
  • Pineal yolk sac tumor may be associated with Down syndrome.[4]
