Abstract A Schwannoma is an infrequent lesion. This tumor derives from the myelin sheath of the peripheral nerves; in most cases, it is benign and rarely presents in the foot and ankle region. Patients affected by this type of pathology are usually asymptomatic. Still, they sometimes have sensory or moto...
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...
El schwannoma es el tumor benigno de nervio periférico más frecuente. Su presencia en los nervios de miembros inferiores es excepcional, donde representan el 1% de todos los schwannomas. Presentamos el caso de una mujer de treinta y un años que consulta por dolor en la cara anterio...
A neurofibromatose tipo 1 é uma doença autossômica dominante
rara, com manifestações clínicas diversas. Sua apresentação
mais marcante é a presença de neurofibromas (tumores da
bainha neural) cutâneos ou internos, que também podem
ocorrer de forma esporádica, associados a outras manifestaç�...

Introduction Schwannomas and neurofibromas are the two most common benign neoplasms of the peripheral nerve sheath, and although they are generally easy to distinguish, in some cases, they can closely resemble one another. Furthermore, malignant peripheral nerve sheath tumors (MPNSTs), another example of...
ABSTRACT Malignant peripheral nerve sheath tumors (MPNST) are very rare and are frequently localized in the buttocks, thigh, arm, or paraspinal region; one variant is the malignant Triton tumor, with rhabdomyosarcomatous differentiation. The authors present a challenging differential diagnosis of a sciat...
Fundamento: el schwannoma espinal es un tumor de las vainas nerviosas y se comporta intradural y extramedular y provienen de las células embrionarias de la cresta neural de los nervios periféricos. Representan entre el 25 y el 30 por ciento de los tumores y afectan a adultos entre 40 y 60, son raros en...
ABSTRACT Objective In this study, we review the institution’s experience in treating malignant peripheral nerve sheath tumors (MPNSTs). A secondary aim was to compare outcomes between MPNSTs with and without neurofibromatosis type 1 (NF1). Methods Ninety-two patients with MPNSTs, over a period ...
