title: Congenital gliosarcoma; so-called sarcoglioma.
abstract: A mixed glioma and sarcoma in a 3-month-old infant is presented as a rare case of gliosarcoma with a good response to treatment. This congenital case is quite different from those in adults: the tumor cells were mainly composed of sarcomatous elements; glial components were not anaplastic without obvious endothelial hyperplasia, but presented as reticulin-free islands, mimicking a reactive glioma in a sarcoma. It may be termed "sarcoglioma" to distinguish from a classic gliosarcoma. The origin of the rare mixed tumor may be related to a dysgenesis of both mesenchymal and glial elements.
