説明

<p>Myxoinflammatory fibroblastic sarcoma (MIFS) is a low-grade malignant soft tissue tumor that typically arises in the distal aspects of the extremities. Although a few cases of the tumors occurring in the nose and eyeball have been reported, MIFS is uncommon in the head and neck region. Herein, we describe a rare case of MIFS arising in the anterior neck. The patient was a 69-year-old woman who presented to our department with a tumor in the anterinr neck measuring 4.4 cm in diameter. Ultrasound-guided fine needle aspiration cytology revealed a poorly differentiated malignant tumor. The tumor was surgically removed, and postoperative histopathology revealed the diagnosis of MIFS. The patient remains recurrence-free one year after adjuvant radiation therapy. The histologic and clinical features of MIFS have been discussed. Because local recurrence is known to occurr in approximately 20% of all reported cases, careful postoperative follow-up is necessary.</p>
