Abstract

Malignant peripheral nerve sheath tumor (MPNST), a rare soft-tissue sarcoma, is most commonly located in the trunk, extremities, and head and neck, but rare in the breast. We report a metastatic breast MPNST in a 27-year-old woman with neurofibromatosis type 1 (NF-1). Chest computed tomography revealed a well-defined, oval, mildly enhancing nodule in the right breast. US revealed a circumscribed, oval, heterogeneous echoic mass with vascularity and intermediate elasticity in the right upper outer breast. The breast mass was excised and diagnosed as MPNST on histopathology evaluation. Although rare, it should be included in the differential diagnosis of breast mass in NF-1 patient.

악성 말초 신경 초종은 드문 연부조직 종양으로, 주로 몸통, 사지, 두경부에 주로 위치하며, 유방에는 드물다. 저자들은 신경섬유종증 1을 가진 27세 여자 환자에서 유방으로 전이된 악성 말초 신경 초종 증례를 보고하고자 한다. 흉부 단층촬영에서 오른쪽 유방에 경계가 분명한 타원형의 약간 조영 증강되는 종괴가 보였다. 초음파에서 혈류와 증등도의 탄성을 가진 경계가 분명한 타원형의 비균질한 에코의 종괴로 보였다. 유방 종괴는 수술로 제거되었고, 악성 말초 신경 초종으로 최종 진단되었다. 드물지만, 악성 말초 신경 초종은 신경섬유종증 1을 가진 환자에서 유방 종괴의 감별진단에 포함되어야 한다.
