Ewing Sarcoma/Peripheral Primitive Neuroectodermal Tumor in the Adrenal Gland of an Adolescent: A Case Report and Review of the Literature

Ewing sarcoma/peripheral primitive neuroectodermal tumors (ES/pPNETs) typically occur in the long or flat bones, the chest wall, extraskeletal soft tissue, or less frequently, in solid organs. They can arise from anywhere in the body; however, ES/pPNETs arising from the adrenal gland are very rare, especially in children and adolescents. Herein, the authors report a case of an ES/pPNET in the adrenal gland of a 17-year-old girl, who was successfully treated with a multimodal treatment, with a brief review of the pertinent literature.
