Ewing sarcoma rarely spreads to the iris. Fine-needle aspiration biopsy can diagnose this rare metastasis, and plaque radiotherapy offers a treatment option for iris tumors.

Area of Science:

  • Ophthalmology
  • Oncology
  • Pathology

Background:

  • Ewing sarcoma is a rare bone and soft tissue cancer.
  • Metastasis of Ewing sarcoma to the eye is uncommon.
  • Iris metastasis presents a diagnostic and therapeutic challenge.

Observation:

  • A 19-year-old woman with metastatic Ewing sarcoma of the femur presented with a diffuse iris mass and pseudohypopyon in the left eye.
  • Fine-needle aspiration biopsy confirmed iris metastasis.
  • Initial treatment with external beam radiotherapy and chemotherapy showed a partial response.

Findings:

  • The iris tumor recurred 5 months after initial treatment.
  • Subsequent treatment with iodine-125 plaque radiotherapy led to further tumor resolution.

  • This case highlights the importance of considering ocular metastasis in Ewing sarcoma patients.

    • Implications:

    • Ewing sarcoma can rarely metastasize to the iris, requiring prompt diagnosis and management.
    • Fine-needle aspiration biopsy is a valuable diagnostic tool for iris metastasis.
    • Plaque radiotherapy is a viable therapeutic option for managing iris metastasis from Ewing sarcoma.
