Ewing sarcoma, a rare orbital tumor, can present in adults with proptosis and bone involvement. Diagnosis requires microscopy and immunohistochemistry, and treatment involves surgery, radiation, and chemotherapy, though outcomes can be poor.

Area of Science:

  • Oncology
  • Ophthalmology
  • Pathology

Background:

  • Orbital tumors can present with proptosis and bone erosion.
  • Ewing sarcoma is typically a pediatric bone tumor, rarely occurring in the orbit of adults.

Observation:

  • A 54-year-old male presented with painful proptosis and an inferolateral orbital mass with bone erosion.
  • Initial investigations ruled out systemic disease.
  • Diagnosis required both light microscopy and immunohistochemistry.

Findings:

  • The patient received chemotherapy, extensive surgical excision, and adjuvant radiotherapy and chemotherapy.
  • Despite aggressive treatment, the patient developed widespread metastatic disease.
  • Death occurred 17 months post-presentation.

Implications:

  • This case underscores the importance of considering Ewing sarcoma in the differential diagnosis of adult orbital round cell tumors.
  • Early and accurate diagnosis is crucial for appropriate management, although prognosis remains challenging.
  • Further research into effective treatments for adult orbital Ewing sarcoma is warranted.
