Abstract

A traumatic neuroma is a tangle of neural fibers and connective tissues which develop at the end of a proximal nerve stump following the nerve injury. The incidence of traumatic neuroma after breast cancer surgery is extremely low, and so far, there are only 11 cases being reported in literature. We present sonographic and pathologic features of a traumatic neuroma that mimics the recurrent breast carcinoma identified on follow-up ultrasound examinations after breast cancer surgery.

  Fig. 1 A 57-year-old woman with traumatic neuroma of the right chest wall who was treated with a right modified radical mastectomy for breast cancer 12 years ago. A, B. Transverse (A) and longitudinal (B) sonogram shows a 0.5 cm-sized, oval-shaped, circumscribed, hypoechoic mass located in the right pectoralis major muscle (arrow). C. The mass shows no vascularity on power Doppler ultrasound. D. Photomicrograph shows haphazardly distributed nerve fascicles surrounded by fibro-adipose tissues which are composed of axons, schwann cells, and some fibroblasts (H&E stain, × 100).
