Abstract

Granular cell tumors (GCTs) are rare soft tissue tumor, originating from neural or perineural cells. We present a case of axillary GCT in a 69-year-old woman with breast cancer history and discuss the various radiologic findings. US revealed a circumscribed oval heterogeneous iso- and hyperechoic mass in the left axilla. Chest CT showed a well-defined, oval, and mildly enhancing mass in the left axilla on the lateral aspect of the pectoralis muscle. A final diagnosis of GCT was made through US-guided core needle biopsy. Follow-up US showed no significant changes in the axillary GCT. Familiarity with GCT may facilitate early diagnosis and subsequent management.

과립세포종은 신경 또는 신경 주위 세포에서 생기는 드문 연부조직 종양이다. 저자들은 유방암 과거력을 가진 69세 여자 환자에서 액와부 과립세포종 증례를 보고하고 다양한 영상 소견을 논의하고자 한다. 초음파에서 왼쪽 액와부에 경계가 분명한 타원형의 비균질한 등에코, 고에코의 종괴였으며, 흉부 전산화단층촬영에서 대흉근의 바깥쪽에 경계가 분명한 타원형의 약간 조영 증강되는 종괴로 보였다. 초음파 유도하 조직 생검을 통해 과립세포종으로 최종 진단되었다. 추적 초음파에서 변화는 없었다. 과립세포종에 대해 잘 알고 있다면 조기 진단과 후속 관리를 용이하게 할 수 있을 것이다.
