Sinonasal undifferentiated carcinoma (SNUC) is a rare and highly aggressive neoplasm of the paranasal sinuses, which has recently been characterized as a distinct pathologic entity. The prognosis for patients with SNUC is poor. There is only case report level information on the usefullness of chemotherapy for this condition and most of these indicate that it is not very effective. Etoposide is supported by a few reports, mostly in combination but without significant reported effectiveness. It can only be considered experimental based on the lack of information and suggestions of it not being effective.
