Traumatic neuromas are more common with SP than ECD. This is due to the limited exposure of the parotid gland with ECD; the greater auricular nerve can be avoided in the dissection in over 60% of cases. There are no established ways of avoiding a traumatic neuroma once the nerve is transected. There are numerous anecdotes and suggestions in the literature but none proven to be effective.
Neurogenic tumors
Published in Eckart Haneke, Histopathology of the NailOnychopathology, 2017
Of the other neurogenic tumors occurring on digits, schwannoma has a different morphology and architecture. Neurofibroma is less myxoid even though myxoid neurofibroma has been observed under the nail. Traumatic neuroma contains nerve bundles often in a myxoid stroma. Perineuriomas are much denser and cellular and are positive for EMA.47

Thus, persistent or recurrent pain in the distribution of the thoracotomy scar in patients with cancer is commonly associated with recurrent tumor. However, a small number of patients will have a traumatic neuroma at the site of their previous thoracotomy scar, but this should not be the initial consideration in evaluating such cancer patients.

Because of the disabling pain, we proposed to attempt surgery to remove the lesion. On surgical exploration under general anesthesia, the sensitive branch of the left medial supraclavicular nerve ended in a hard mass, apparently in continuity with an ectatic left transverse cervical artery (Figure 2a). The accessory nerve was not involved but in close anatomical relation with it (Figure 2b). Due to the resemblance to a thrombosed pseudoaneurysm related to a traumatic neuroma, the arterial branches were ligated and the lesion was radically excised. Histopathological evaluation showed a mesenchymal neoplasm with both spindle and epithelial cells, some mitotic Figures (1–2 x 10 HPF), and absence of necrosis (Figure 3a,b). Immunohistochemistry stain highlighted a heterogeneous labeling index Ki67 of 4% and positivity of actin-ML and collagen type IV (Figure 3c–e). Despite the preoperative suspicion and the intraoperative appearance, the histological examination revealed a glomangiomyoma. An uneventful postoperative recovery was noted and the painful symptoms promptly regressed after surgery. No recurrence has occurred after 18 months of follow up.

However, for serious nerve injury with large gaps, nerve grafts must be implanted to fill the nerve defect [8,9]. Autologous nerve transplantation is considered as the gold standard for peripheral nerve repair because it can provide the basement membrane tube needed for the growth of axons with small immune rejection [5,8]. Autologous nerve transplantation still has many problems, such as insufficient sources, difficulty in meeting the requirements of long-term neurological deficits, new lesions and loss of function left after the donor site is removed, and artificially formed traumatic neuroma, sensory disturbance and loss of function [10]. Therefore, the development of artificial nerve grafts is considered as a promising alternative to autologous nerve grafts [11].
Resolution of persistent traumatic supraorbital pain after neuroma excision

Histologic analysis of the surgical specimen demonstrated hyperplastic tortuous nerve bundles with focal convolution, consistent with traumatic neuroma (Figure 2). After surgery, the patient experienced an immediate resolution of pain and migraines. At a 6-month follow-up, the patient was still pain free. However, as a result of surgical resection of the supraorbital nerve, the patient had residual hypoesthesia in the region of V1 distribution. The remainder of his postoperative course was uneventful.
