Abstract

Myxofibrosarcoma (MFS) is a rare subtype of soft tissue sarcoma, most commonly occurring in the lower extremities and rarely in the head and neck region. To our knowledge, there have been no reported cases of MFS originating from the maxillary sinus in Korea. Herein, we describe a case of a 61-year-old male who presented with left-sided hypoesthesia and a mass in the maxillary sinus, which was subsequently diagnosed as MFS originating from the maxillary sinus through endoscopic surgery with a prelacrimal approach. The patient was administered postoperative radiation therapy, and after two years of follow-up, there was no evidence of recurrence. This report presents a case of successful treatment of MFS in the maxillary sinus.
