Although the exact histogenesis is still unknown, various cells have been proposed as cells of origin namely, endothelial, hematopoietic, fibroblastic, mesenchymal stem cells or neural derived mesenchymal stem cells. ES is more common in younger age group and among the gnathic bones, mandible is affected more than maxilla. This paper presents the first case of Ewing Sarcoma in the maxilla being reported in the adult age group from India and among the very few reported worldwide.
尤因肉瘤是一种罕见的儿童恶性骨与软组织肉瘤，在头颈部更为少见。尽管确切的组织发生学仍不清楚，但已提出多种细胞作为起源细胞，即内皮细胞、造血细胞、成纤维细胞、间充质干细胞或神经源性间充质干细胞。尤因肉瘤在较年轻年龄组中更为常见，在颌骨中，下颌骨比上颌骨更易受累。本文报道了印度成年年龄组中首例上颌骨尤因肉瘤病例，这也是全球为数不多的报道之一。
