Uncovering a Novel Site of Ewing's Sarcoma: the Hypopharynx.

Ewing's sarcoma is usually seen in bones but 20-30% are found in extra skeletal soft tissues like in head and neck region. We present the case of Ewing sarcoma of hypopharynx in a 1 year old child who presented to us with acute respiratory distress. Child was intubated using videolaryngoscope and mass was removed using microdebrider. Final histopathological examination revealed Ewing sarcoma. EWSR1 gene rearrangement studies were advised, which the patient refused. Post-operative patient was started on adjuvant chemotherapy. PET CT after 2 months showed no FDG avid lesions within or elsewhere in the region of the body surveyed. There is no case of Ewing's sarcoma in hypopharynx reported to date. The clinical presentation, management and outcome has been discussed with a review of the literature.
