Primary Ewing's sarcoma of the anterior fontanelle in a neonate.

Primary cranial Ewing`s sarcoma is extremely rare. We present a case of primary Ewing's sarcoma of the skull in a neonate that involved the anterior fontanelle and was very aggressive in nature. Even with radical surgery, the patient had early recurrence within 2 months of surgery and ultimately died. Detailed radiological and pathological findings are described.
