Ewing's sarcoma is a bone tumor that rarely arises in the head and neck region. Head and neck tumors account for only 2% to 3% of all Ewing's sarcomas. There is an extremely rare subgroup of Ewing's tumors, that are histologically indistinguishable, which are not metastatic and arise in soft tissue rather than bone. Two Ewing's sarcomas of the nose are described. One case is the first reported nasal Ewing's soft tissue sarcoma. The other case is the more traditional type involving bone of the nose and extending into ethmoid sinuses and intracranially.
尤因肉瘤是一种很少发生于头颈部的骨肿瘤。头颈部肿瘤仅占所有尤因肉瘤的2%至3%。尤因肿瘤中有一个极其罕见的亚组，在组织学上无法区分，不发生转移，且发生于软组织而非骨组织。本文描述了两例鼻部尤因肉瘤。一例是首例报道的鼻腔尤因软组织肉瘤。另一例是更传统的类型，累及鼻骨并延伸至筛窦和颅内。
