Key result
A 35-year-old woman with a painful abdominal wall tumefaction was diagnosed with an extraskeletal Ewing sarcoma in the left anterolateral muscle group following imaging and surgical biopsy.
Case Report (n=1)
Extraskeletal Ewing sarcoma can exceptionally present as a soft tissue mass in the abdominal wall, requiring histological diagnosis.
Rare abdominal wall masses warrant sarcoma consideration in differentials; leaves open optimal diagnostic and therapeutic strategies for atypical sites.
Ewing sarcoma is most commonly a bone tumour which has usually extended into the soft tissues at the time of diagnosis. Exceptionally, this tumour can have an extraskeletal origin. Clinical or imaging findings are non-specific and diagnosis is based on histology. We report a case of an extraskeletal Ewing sarcoma developed in the soft tissues of the abdominal wall in a 35-year-old woman who presented a painful abdominal wall tumefaction. Ultrasongraphy and computed tomography showed a large, well-defined soft tissue mass developed in the left anterolateral muscle group of the abdominal wall. Surgical biopsy was performed and an extraskeletal Ewing sarcoma was identified histologically.

A. Askri (2008) conducted a case report in Extraskeletal Ewing sarcoma of the abdominal wall (n=1). Surgical biopsy and imaging was evaluated on Diagnosis of extraskeletal Ewing sarcoma. A 35-year-old woman with a painful abdominal wall tumefaction was diagnosed with an extraskeletal Ewing sarcoma in the left anterolateral muscle group following imaging and surgical biopsy.
