Traumatic neuroma at the mastectomy site, unusual benign lesion, mimicking tumor recurrence: A report of two cases

Abstract

Traumatic neuroma is not a true neoplasm but a reparative proliferation of axons, Schwann cells, and fibroblasts at the proximal end of transected or injured nerves resulting from trauma or surgery. Breast traumatic neuroma after breast surgery, with or without clinical symptoms, has rarely been reported. Once found, it should be differentiated from tumor recurrence, and tissue confirmation is necessary, although it is small in size and demonstrates a benign appearance in imaging studies. Herein, we present two cases of traumatic neuroma at the mastectomy site. They were incidentally encountered during ultrasound evaluation of mastectomy beds given concerns for potential recurrence or malignancy, and pathologic confirmation by ultrasound-guided core needle biopsy was sufficient for the diagnosis.

Biliary tree traumatic neuroma following laparoscopic cholecystectomy: A case report and literature review

“…Traumatic neuroma is a rare, non-neoplastic lesion that forms at the proximal end of a damaged nerve following trauma or surgery, as a healing process involving the hyperplastic proliferation of nerve fibers and connective tissue ( 1 ). Although it is a common pathology following trauma and surgeries, it is rarely reported in clinical practice ( 2 ).…”

“…The lesion can develop after any surgery, particularly an amputation ( 3 ). The lower extremities are the most frequent site of occurrence, followed by the head and neck, radial nerve and brachial plexus ( 1 ). A biliary neuroma is a relatively rare benign tumor that can be classified into two types: Primary and traumatic neuromas ( 4 ).…”
