Ewing Sarcoma/Peripheral Primitive Neuroectodermal Tumor in an Adolscence, Manifested as Isolated Cervical Mass / 임상소아혈액종양

ABSTRACT

Ewing sarcoma/peripheral primitive neuroectodermal tumor (ES/PPNET) arises from bone or soft tissue of many sites of body, but ES/PPNET, as primary lesion, in the soft tissue of neck is very uncommon. The authors experienced a case of ES/PPNET in a 17-year-old girl, which was manifested as isolated cervical mass in the soft tissue without any other suspected primary lesion or metastasis. We report the case with a brief review of the literature.
