Ewing’s Sarcoma

Abstract

Ewing’s sarcoma is a malignant bone tumor histologically formed by round blue cells and is among the most aggressive tumors found in children. Its incidence is low and all bones can be affected. Local pain and swelling are common signs of presentation. There are sometimes inflammatory signs such as fever and a macroscopic aspect looking like pus, thus mimicking infectious presentation. The presence of metastasis is high at the moment of the diagnosis. Imaging can be characteristic with soft tissue involvement, which can be massive. Histology and cytogenetics make the final diagnosis. Treatment must be performed by a team of specialists dedicated to sarcoma management. Multidrugs chemotherapy, sometimes radiotherapy and surgery are indicated for the systemic and local control of the disease. The expected survival rate is around 70% at five years of age when the patient is properly treated.
