후이개에 생긴 저악성 근섬유아세포 육종 1예

Low grade myofibroblastic sarcoma is recently described as representing malignant mesenchymal tumor that shows myofibroblastic differentiation; few cases have been reported. We report a case of a 37-year-old patient with mass on the postauricular area. Based on histological and immunohistochemical evidence, the diagnosis of low grade myofibroblastic sarcoma was established. This paper has clinical significance because this is the rare case of low grade myofibroblastic sarcoma of the head & neck in Korea. (J Clinical Otolaryngol 2010;21:253-256)
