Ewing's sarcoma of the nose.

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.
