Overview

NCI Definition: A small round cell tumor that lacks morphologic, immunohistochemical, and electron microscopic evidence of neuroectodermal differentiation. It represents one of the two ends of the spectrum called Ewing sarcoma/peripheral neuroectodermal tumor. It affects mostly males under age 20, and it can occur in soft tissue or bone. Pain and the presence of a mass are the most common clinical symptoms. [1]

Ewing sarcomas most frequently harbor alterations in EWSR1, FLI1, TP53, STAG2, and CDKN2A [2].

Most Commonly Altered Genes in Ewing Sarcoma

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 c.142-c.212 Missense, TP53 c.1-c.137 Missense, and TP53 Missense are the most common alterations in Ewing sarcoma [2].
