Prabowo Y, Hadinoto HA. Primary cutaneous Ewing’s sarcoma/primitive neuroectodermal tumor manifested as huge ulcerated mass on posterior thigh region: Case report and review of literature. J Case Rep Images Orthop Rheum 2018;3:100015Z14YP2018.ABSTRACT
Introduction: Ewing’s Sarcoma (ES) and Primitive Neuroectodermal Tumor (PNET) are thought to have a common origin as these tumors share identical clinical and histological properties and are often interchangeably used in literatures. Extraskeletal ES/PNET is rarely found especially on cutaneous region and primarily manifests as a single small lesion in the mid-to-deep dermis.
Case Report: We reported an unusual presentation with MRI findings of cutaneous ES/PNET case on 19-year-old presenting as a single huge ulcerated mass that was initially mistaken as arteriovenous malformation.
Conclusion: Magnetic resonance imaging provided excellent depiction in suggesting the diagnosis of cutaneous ES/PNET. Surgical excision followed by chemotherapy were successful in treating this case with no local recurrence or distant metastasis was observed after one year of follow-up.
