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.
