EXTRA SKELETAL PANCREATIC EWING SARCOMA CASE REPORT

Pancreatic extra-skeletal Ewing sarcoma (EES) is an aggressive mesenchymal soft-tissue tumor that accounts for 1% of all soft-tissue sarcomas and 2% to 5% of malignant bone neoplasms. Ewing sarcoma (ESB) was initially characterized by James Ewing in 1921.[1] It can be identified when the soft-tissue tumor has a sarcomatous appearance with an osteoid or cartilage matrix but no underlying bony connection.[2] With a median age of 66 years, this uncommon tumor affects men and women equally in the fifth and sixth decades of life, in contrast to osteosarcoma of the bone, which primarily occurs in the first two decades.[3-5]
