Ewing sarcoma (EWS) is a rare bone cancer. This case study details a challenging diagnosis and treatment of EWS in the paranasal sinuses, highlighting its rarity and complexity.

Area of Science:

  • Oncology
  • Head and Neck Surgery
  • Pediatric Oncology

Background:

  • Ewing sarcoma (EWS) is a rare malignant bone tumor predominantly affecting children and young adults.
  • While typically found in long bones, EWS can rarely occur in the head and neck, including the paranasal sinuses.

Purpose of the Study:

  • To present a challenging case of EWS in the paranasal sinuses.
  • To discuss the diagnostic and management difficulties associated with this rare presentation.

Main Methods:

  • Case report of a 45-year-old female with EWS of the sphenoidal and right nasal fossa.
  • Surgical subtotal mass removal.
  • Adjuvant radiotherapy and chemotherapy.
