Traumatic Neuroma in a Breast Cancer Patient After Modified Radical Mastectomy: A Case Report

Abstract

Traumatic neuromas are rare benign lesions that develop from non-neoplastic proliferation of axons, schwann cells, and fibroblasts at the proximal end of transected or injured nerves as a result of trauma or surgery. We present the case of a traumatic neuroma in a 47-year-old female who was treated with a right modified radical mastectomy for breast cancer 14 years ago. Ultrasound examination revealed an oval-shaped hypoechoic nodule at the 9-o’clock position in the right chest wall. Color Doppler imaging showed no increased blood flow and a positron emission tomography-computed tomography examination revealed no fluorodeoxyglucose uptake in this nodule. The typical histologic findings were present.

외상신경종은 외상이나 수술 후 손상된 신경의 근위부에서 신경축삭, 슈반세포 및 섬유모세포가 비종양성 증식을 하는 것으로 매우 드문 양성 질환이다. 저자들은 유방암으로 14년 전에 변형근치유방절제술을 시행한 47세 환자의 흉벽에서 발생한 외상신경종을 보고하고자 한다.
