Extra-skeletal Ewing sarcoma is rare, but can present unusually. This case highlights a 66-year-old man whose intermittent melena led to diagnosis of a small bowel Ewing sarcoma via capsule endoscopy.
Area of Science:
- Oncology
- Gastroenterology
- Surgical Pathology
Background:
- Ewing sarcoma is a primary bone malignancy.
- Uncommon extra-skeletal presentations can mimic other pathologies.
Observation:
- A 66-year-old male presented with intermittent melena.
- Capsule endoscopy revealed a small bowel neoplasm.
- The patient developed a secondary small bowel obstruction.
Findings:
- The neoplasm was diagnosed as an extra-skeletal Ewing sarcoma.
- Surgical resection and surveillance were performed.
- The patient achieved a complete remission with no evidence of disease at four years.
Implications:
- This case expands the differential diagnosis for gastrointestinal bleeding and obstruction.
- Highlights the importance of considering rare malignancies in older adults.
- Demonstrates successful management of extra-skeletal Ewing sarcoma.
