Extraskeletal Ewing's sarcoma presenting with neurological symptoms. Report of two cases

Extraosseous Ewing's sarcoma (EES) is an uncommon condition that may develo p in soft tissues at any location. Neurological symptoms leading to diagnos is have been reported exceptionally. We report two cases of EES in patients aged 16 and 74 years, presenting with cauda equina syndrome and radicular ulnar involvement respectively. Radiological images showed a paraspinal mas s in both cases and biopsy disclosed the histological features of Ewing's s arcoma. EES should be kept in mind in the differential diagnosis of paraspi nal soft tissues tumours at any age.
