Yolk Sac Tumor : Myxomatous Pattern

slide 4 of 16


Comments:
Myxomatous pattern of Yolk Sac Tumor shows neoplastic stellate, spindle, or epithelioid cells in abundant myxoid stroma. Many of these cells are pluripotential and can form muscle, cartilage, and bone. Such areas should not be confused with teratoma. The pluripotential mesenchymal cells are chemoresistant and in rare cases can give rise to sarcoma after treatment.
