Summary
A rare case of extraskeletal Ewing's sarcoma in a young man presented with abdominal pain and a mass. Surgical removal and chemotherapy led to an 18-month tumor-free outcome.
Area of Science:
- Oncology
- Surgical Pathology
Background:
- Extraskeletal Ewing's sarcoma (EES) is a rare malignant bone tumor.
- EES typically affects the trunk and extremities, with pelvic and abdominal presentations being less common.
Observation:
- A 25-year-old male presented with acute right lower quadrant abdominal pain and a palpable mass.
- Imaging and subsequent surgical exploration revealed a tumor involving the abdominal wall, seminal vesicle, ureter, and bladder.
Findings:
- Histologic examination confirmed the diagnosis of extraskeletal Ewing's sarcoma.
- Surgical resection included the tumor, right seminal vesicle, adjacent ureter, and bladder wall.
- No tumor invasion was identified within the seminal vesicle itself.
Implications:
- This case highlights the importance of considering EES in the differential diagnosis of abdominal masses in young adults.
- Successful management involved a multidisciplinary approach combining radical surgery and adjuvant chemotherapy.
- The patient achieved a favorable outcome with no evidence of recurrence at 18 months post-treatment, suggesting the efficacy of combined therapy.
