Treatment of Patients With Extraskeletal Ewing Sarcoma in the Scapular and Arm Regions With Wide Resection: A Report of Two Cases and Literature Review

Figure 1. The preoperative magnetic resonance imaging (MRI) of the first patient, a 60-year-old female, demonstrates a lesion within the soft tissue of the left scapular region. The white arrows indicate the mass in the interscapular region.

Figure 2. Intraoperative images of the first patient showing the lesion removed through wide resection, including the previous biopsy tract. (A) Image of the lesion before removal, (B) image during the removal of the lesion, and (C) image after the lesion was removed.

Figure 3. Preoperative magnetic resonance imaging (MRI) of the second patient, an 18-year-old female, showing the lesion located in the left shoulder region, surrounding the biceps brachii muscle: (A,B,C,F) sagittal and (D,E) axial MRI sections. The white arrows indicate the lesion surrounding the biceps, triceps, and brachioradialis muscles.

Figure 4. Intraoperative images of the second patient, showing the lesion with invasion involving the brachialis, biceps brachii, and triceps brachii muscles. (A) Images showing the vascular structures carefully separated from the surrounding muscle tissue, (B) a pre-resection image of the mass, and (C) the preservation of vascular structures during the resection of the biceps and brachialis muscles.

Figure 5. Intraoperative images of the second patient following wide resection surgery: (A) pre-resection and (B) post-resection images.
