Peripheral Nerve Schwannomas: A Literature Review
Arq. bras. neurocir; 38 (4), 2019
Publication year: 2019
Introduction Schwannomas are benign tumors originating from the cells, which wrap
around axons that are usually encapsulated and solitary. These tumors usually lead to little
or no symptomatology. They are usually the most common peripheral nerve tumors in
adults, with their highest incidence between the third and fifth decades of life.
Objective To perform a review about schwannoma of the peripheral nerves, presenting
its definition, epidemiology, diagnosis, symptomatology and treatment.
Methodology This is a descriptive work, based on a review of articles available in the
PubMed database with the descriptors schwannoma and peripheral nerves.
Results and Discussion Only papers published between 1981 and 2019, describing
studies in humans, and that were available as full articles were selected. A total of 391
articles were included; after reading the titles, we noted that 67 articles fit the topic of
the present study. Among the articles selected for reading, 33 fit the objectives of the
present work, and were considered for the writing of the present article.
Conclusion Schwannomas are benign myelin sheath tumors that develop with local
symptomatology or asymptomatic and present a good surgical prognosis with
generally reduced rates of surgical complications.
