A Case of Extraskeletal Ewing Sarcoma Treated With Wide Local Excision With Latissimus Dorsi Flap and Systemic Therapy.

Extraskeletal Ewing sarcoma (EES) is a rare tumor of the soft tissue that looks the same as skeletal Ewing sarcoma (ES). A male in his 50s was diagnosed with extraskeletal Ewing sarcoma (EES) of the right shoulder, which had infiltrated the muscles around the shoulder joints. Although uncommon, all members of the ES family of tumors, including EES, were treated following the same general protocol for sarcoma tumors. Due to the significant tumor size in this patient and local invasion, wide local excision and a latissimus dorsi flap were required. This case highlighted the management of EES, including the surgical removal of the mass on the right shoulder, followed by chemotherapy, which led to a successful outcome.
