Abstract Posterior interosseous nerve syndrome is the most frequent syndrome of radial nerve compression, with the arcade of Frohse being the main site of compression. Its symptoms include difficulties in finger and wrist extension with possible radial deviation. Herein, we present a case of posterior in...
Benign tumors of peripheral nerves called Schwannomas or neurilemomas, correspond to a rare pathology, represent 5% of all tumors of the upper extremity, and affects, mainly, the ulnar nerve. The incidence of Schwannoma in the literature for the radial nerve is not clearly established given the infrequen...

Puede ser causada por fricción, conllevando la aparición de callosidades, inflamación crónica, eccema o trastornos genéticos...
Paragangliomas are rare, benign and slow-growing neuroendocrine tumors that can
arise from the adrenal medulla (85–90%) or from the extra-adrenal paraganglia.
In the central nervous system (CNS), they can be found at several sites, but more often
at the cauda equina and filum terminale region, where th...
Schwannomas are benign tumors of the peripheral nerve sheath originating from Schwann cells, which can manifest in head and neck regions and are rare in the oral cavity, especially their involvement in the maxillary alveolar ridge, which is even more atypical. Among all its variants, plexiform schwannom...
Introdução: O schwanoma é um tumor pouco frequente que se origina das células de Schwann que recobrem os prolongamentos nervosos. A malignidade desses tumores é ainda mais rara, correspondendo a 5-10% de todos os sarcomas. O prognóstico é reservado, mesmo após completa ressecção cirúrgica. Rel...

Introduction Primary nerve tumors correspond to 5% of the soft tissue neoplasms
affecting the upper limbs, with benign lesions being more frequent than malignant
lesions.
Objective To describe the epidemiological data of the microsurgical treatment of
peripheral nerve tumors performed by the Brazilian U...
ABSTRACT Objective: The aim of this study was to describe the strategies adopted in this institution to diagnose and treat patients with benign tumors affecting the median nerve. Methods: A retrospective chart review study of all patients operated on between 2010 and 2015. Histology, symptoms, compleme...
