Microscopically, they demonstrate hyalinization and thrombosis of the blood vessels and mucinous degeneration of the nerve and nerve sheath, which gives rise to fibrosis over time (Figure 52.2a) (Scheithauer et al., 2010). Usually nerves can repair themselves by proximal to distal proliferation of Schwann cells; when this reparation is interrupted or cannot occur in an orderly manner, the proximal aspect of the nerve creates a disorganized proliferation of nerves, that is, a neuroma. 2011 Apr;36(4):686-94. doi: 10.1016/j.jhsa.2010.12.023. 2015 May;31(2):319-38. doi: 10.1016/j.hcl.2015.01.006.

Julie C. Fanburg-Smith, in Bone and Soft Tissue Pathology, 2010. (b) Pacinian neuroma composed of enlarged pacinian corpuscle with additional circumferential rings and degenerative change. COVID-19 is an emerging, rapidly evolving situation. Figure 16. Plast Reconstr Surg Glob Open. Treatment techniques range from simple aspiration to resection depending on the size and location of the lesion.

2013 Oct;66(10):1330-4. doi: 10.1016/j.bjps.2013.06.019. Plast Reconstr Surg Glob Open. The histologic findings are most consistent with recurrent nerve trauma, most probably resulting from the wearing of poorly fitting shoes. Neuromas of a digital nerve after amputation can produce a tender stump and will require desensitization. Relocation Nerve Grafting: A Technique for Management of Symptomatic Digital Neuromas.

These lesions have a thick, fibrous wall that contains a cystic space that is either unlined or lined by a thin layer of bland-appearing cells, leading to the designation of pseudocyst or cyst, respectively. Novel Use of Targeted Muscle Reinnervation in the Hand for Treatment of Recurrent Symptomatic Neuromas Following Digit Amputations. Mean time to surgical intervention was 11 months. They have a predilection for the head, neck, and flexor surfaces of the upper and lower extremities. The first is the spindle type, which is due to chronic friction to the nerve at a point of irritation or microtrauma due to stretching or compressing of the nerve by localized scar tissue.

Treatment of painful neuroma of amputated phalanx with distal toe transfer: a case report. Microscopically, they consist mostly of bundles or fascicles of cytologically normal spindled Schwann cells that are aligned with fewer numbers of normally appearing axons (Figure 52.2c). Antoni B areas are far less cellular; the spindled or oval cells are arranged haphazardly within the loosely textured matrix, which is punctuated by microcystic change, inflammatory cells, and delicate collagen fibers.

Of 1,083 patients, 71 (6.6%) developed a symptomatic neuroma. Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. FIG.  |  21-38). J Hand Microsurg. Novel Use of Targeted Muscle Reinnervation in the Hand for Treatment of Recurrent Symptomatic Neuromas Following Digit Amputations. Plast Reconstr Surg Glob Open. Pain that is associated with a neuroma does not always have a precise topography and is often difficult to distinguish from phantom limb pain. Grossly the lesions are circumscribed, white-gray nodules located in continuity with the proximal end of the injured or transected nerve. Unlike schwannomas (which are composed solely of neoplastic Schwann cells), neurofibromas consist of a heterogeneous population of Schwann, perineurial-like, and fibroblastic cells. Most commonly, it shows interlacing bundles of elongated cells with wavy, dark-staining nuclei with intercellular wire-like strands of collagen and small to moderate amounts of mucoid material that separate the cells and collagen. Neurilemoma is an encapsulated nerve sheath tumor that consists histologically of two components: (1) a highly ordered cellular component (Antoni A area) and (2) a loose myxoid component (Antoni B area). Results: Spindle-type traumatic neuroma of the common peroneal nerve. Mucosal neuroma also has a unique clinical setting with multiple endocrine neoplasia type 2b (MEN-2b), which is not associated with traumatic neuroma. Usually nerves can repair themselves by proximal to distal proliferation of Schwann cells; when this reparation is interrupted or cannot occur in an orderly manner, the proximal aspect of the nerve creates a disorganized proliferation of nerves, that is, a neuroma. Management of complications relating to finger amputation and replantation. These are internal focal fusiform swellings (Figure 16). There is variable enhancement following intravenous Gd (Figure 18).43–45. Traumatic neuromas can occur after amputation of a limb or autoamputation of a digit in utero. Clipboard, Search History, and several other advanced features are temporarily unavailable. Because both MEN2A and MEN2B have strikingly high rates of death from multifocal medullary thyroid cancer, early recognition is crucial to allow surgical removal of the thyroid before the development of cancer (Wohllk et al., 2010).

(b) Normal peripheral nerve (left) transitions to a traumatic neuroma (right) consisting of haphazardly arranged bundle of nerve fibers in a dense collagenous background. This site needs JavaScript to work properly. At surgery, a fusiform swelling proximal to the bifurcation of the plantar interdigital nerve is usually seen. A total of 47 patients (66%) underwent surgery for painful neuroma. Complete excision is curative in most cases. These lesions are commonly found on the fingers and less commonly on the toes of middle-aged adults in association with local trauma (Fletcher & Theaker, 1989). Disorganized proliferation of nerve in response to injury or disruption, Any nerve that has been surgically or autoamputated, especially the limbs and digits, Observation of bulbous end of truncated nerve, Benign reactive; treatments include prior reapproximation of nerve, removal, or re-embedding of proximal nerve stump, Small, firm, gray–white nodule at site of interrupted nerve, Proliferation of small nerve twigs with surrounding fibrosis, PEN, mucosal neuroma, Morton's neuroma, and neurofibroma. Digital amputation; incidence; neuroma; revision amputation; traumatic amputation.

Hand Clin.

The most common setting is postsurgical in both external soft tissue and visceral sites. We tested the null hypothesis that no factors are independently associated with the development of symptomatic neuroma after traumatic digital amputation. By continuing you agree to the use of cookies. South Med J. With CT scanning, the attenuation is that of muscle and hence non-specific [38].

Ultrastructural analysis of the cyst lining suggests that these lesions contain cells with myofibroblastic differentiation similar to those that compose the synovial joint capsule (Scherman, Bilbao, Hudson, & Briggs, 1981). Secondary Surgery following Initial Replantation/Revascularization or Completion Amputation in the Hand or Digits.

doi: 10.1097/GOX.0000000000002376. Generally, the S100 stain is much less intense than in neurilemoma. 4-38). They present as unilateral lesions, mostly in adult females, on the plantar surface between the metatarsals of the foot between the third and fourth, or less commonly between the second and third toes (Wu, 1996).
