Ewing sarcoma is most commonly a bone tumor which has usually extended into the soft tissues at the time of diagnosis. Exceptionally, this tumor can have an extra-skeletal origin. Clinical or imaging findings are nonspecific and diagnosis is based on histology. We report a case of an extra-skeletal Ewing sarcoma developed in the soft tissues of the inguinal region in a 28-year-old man who presented a painless right inguinal mass for 2 months. Ultrasonography showed a large, well-defined soft tissue mass developed in the right inguinal region with tender inguinal Lymph Node (LN) Surgical biopsy was performed, and an extra skeletal Ewing sarcoma was identified histologically.
