Primary Extraosseous Ewing Sarcoma of Anterior Abdominal Wall (original) (raw)
2017, Indian Journal of Gynecologic Oncology
Ewing's sarcoma (ES) is the second most common malignant bone tumor in children and young adults. ES also occurs as a primary soft tissue neoplasm without involvement of bone. Usual sites of involvement are the deep soft tissues of the lower extremity and paravertebral region. Clinical or imaging findings are non-specific, and diagnosis is based on histology. We reported a rare case of an Extraosseous Ewing Sarcoma (EES) developed in the soft tissues of the anterior abdominal wall in midline position in a 63-year-old woman who presented with a painful abdominal mass. The case was suspected to be carcinoma ovary with pelvic deposits, however on laparotomy it was found to be a malignant anterior abdominal wall mass. The final diagnosis on immunohistochemical staining was EES.
