ABSTRACT
ABSTRACT INTRODUCTION:
Peripheric nerve tumors typically derive from Schwann cells of the peripheral nerve sheet. Since these tumors are uncommon, they should be considered in preoperative differential diagnosis.OBJECTIVE:
To report the experience of a tertiary care department.METHODS:
Forty-two patients with head and neck peripheral neurogenic tumors were retrospectively analyzed and evaluated from 1977 to 2013. The preoperative diagnosis was confirmed by biopsy or imaging study.RESULTS:
The mean age was 41.7 and 15 patients (36%) were male. The mean size was 5.5 cm and 26 (61%) were located laterally in the neck. Most tumors (39.9%) presented as an asymptomatic neck mass. Most (39.9%) were resected through a neck approach. Cranial nerves were the commonest site of origin.CONCLUSIONS:
Extracranial neurogenic tumors presented with a mean size of 5.5 cm, were located laterally in the neck, normally had their origin from cranial nerves, and their resection approach is cervical.RESUMO
Resumo INTRODUÇÃO:
Tumores dos nervos periféricos tipicamente derivam das células de Schwann da bainha dos nervos periféricos. Por serem incomuns, devem ser lembrados no diagnóstico diferencial pré-operatório.OBJETIVO:
Relatar a experiência de serviço de referencia terciária.MÉTODO:
De 1977 a 2013, 42 pacientes com tumores neurogênicos periféricos da cabeça e pescoço foram operados e analisados retrospectivamente. A confirmação diagnóstica pré-operatória deu-se por biópsia ou método de imagem.RESULTADOS:
A média da idade foi de 41,7 anos, sendo 15 indivíduos (36%) do gênero masculino. O tamanho médio foi de 5,5 cm e 26 (61%) localizavam-se na face lateral do pescoço. A maior parte (39,9%) apresentou-se como tumor palpável assintomático. A maioria (39,9%) foi ressecadapor acesso cervical. A maioria originou-se de nervos cranianos.CONCLUSÕES:
Tumores neurogênicos extracranianos apresentam-se com tamanho médio de 5,5 cm, na face lateral do pescoço, costumam originar-se de nervos cranianos e ser ressecados por via cervical.
