Abstract
BACKGROUND: Sinonasal localization of Ewing's sarcoma in adults is an exceedingly rare event.
METHODS: The clinical records of 5 patients with primary sinonasal Ewing's sarcoma treated from 1992 to 2012 were retrospectively analyzed. All pathologic slides were reviewed by 2 experienced pathologists. All patients underwent multimodality treatments.
RESULTS: Median age was 36 years (range, 25-52 years). At referral, 2 patients had the original diagnosis changed by review of the histologic slides. Tumors were classified as T4aN0M0 (4 patients) and T2N0M0 (1 patient). Median follow-up was 110 months (range, 70-139 months). Only 1 patient, who started treatment elsewhere based on an incorrect histologic diagnosis, experienced multiple recurrences and eventually died of widespread metastasis.
CONCLUSION: Correct pathologic diagnosis can have a crucial impact on treatment planning and outcome. Multimodality therapy is the key for long-term successful results. Because of the rarity of the tumor, referral to highly experienced care centers is strongly recommended. © 2016 Wiley Periodicals, Inc. Head Neck, 2016.
