Primary Ewing's Sarcoma of Zygoma

Ewing's sarcoma is a small round cell tumor, malignant in nature, typically affecting long bones and pelvis. It is most commonly presented in the pediatric age group. The occurrence of Ewing's sarcoma in the head-and-neck region is rare and is reported to be around 2%–3%, of which chances of having primary lesion are rarer. Among facial bones, mandible is the most commonly affected bone. Primary involvement of zygoma is extremely rare. Here, we present a case of primary Ewing's sarcoma of the left zygoma in a 17-year-old girl. The diagnosis was made after surgical resection, histopathology with immunohistochemistry confirmation, and cytogenetic study.
