Abstract
|
|
|
|
Undifferentiated pleomorphic sarcoma (UPS) is a rare soft tissue sarcoma of the sinonasal area. Here, we present two primary cases of UPS and three post-irradiation sinonasal UPS cases. Imaging findings were misinterpreted by radiologists as representing other malignant tumors or recurrence of the primary tumor. Our cases indicate that post-irradiation UPS can originate within any part of the radiation field. Treatment outcomes of primary sinonasal UPS seem to be favorable if the tumor is treated aggressively, but the outcomes of post-irradiation sinonasal UPS may be poor if appropriate surgical margins cannot be obtained.
