This report details a rare case of extraskeletal Ewing's sarcoma in a 16-year-old female, originating in the maxillary sinus and extending to the orbit. The patient successfully responded to chemotherapy and radiotherapy, showing no recurrence after one year.

Area of Science:

  • Oncology
  • Head and Neck Surgery
  • Radiology

Background:

  • Extraskeletal Ewing's sarcoma (EES) is a rare malignancy, infrequently occurring in the head and neck region.
  • Invasion of the nasal cavity or paranasal sinuses by EES is exceptionally uncommon, with only six prior reports.

Observation:

  • A 16-year-old female presented with right cheek swelling, normal nasal examination.
  • Imaging (CT and MRI) revealed a large mass in the right maxillary sinus extending into the orbit, without nasal involvement.

Findings:

  • Histopathological analysis confirmed extraskeletal Ewing's sarcoma.
  • The patient declined surgery but received combined chemotherapy and radiotherapy.

Implications:

  • This case represents the first documented instance of EES in an isolated maxillary sinus extending to the orbit.
  • The successful treatment outcome highlights the potential efficacy of non-surgical management for this rare presentation.
