A Case of Primary Ewing's Sarcoma of Arising from the Nasal Cavity / 대한이비인후과학회지

Ewing's sarcoma is an uncommon malignancy that usually occurs in children. It most commonly involves the lower extremity, with the pelvis being the next most common site. Primary Ewing's sarcoma that arises in the head and neck region is extremely rare, representing only 1-4% of all Ewing's sarcoma cases. We report a case of primary Ewing's sarcoma in the nasal cavity in a 10-year old patient with a non-specific past medical history, in which the patient received 3 trials of neoadjuvant chemotherapy, endoscopic wide excision, followed by 2 more trials of adjuvant chemotherapy. Currently, it has been 5 years since treatment and the patient did not exhibit any signs or symptoms of recurrence of the disease.
