@entity808 @entity1 @entity5
@entity808 are relatively rare @entity5 that arise from Schwann cells of the sheaths of peripheral nerves. They may be found in any portion of the body. In reported series of @entity808 , the percentage of @entity5 in the head and neck varies from 16% to 45%. Usually demonstrating slow growth, they often have a history of long duration, and are most often diagnosed in adults. Approximately 10% of @entity808 are diagnosed in @entity1 under 21 years of age. In this paper two @entity1 with large @entity808 of the head and neck are reported. In both, the symptoms were of relatively short duration, but physical findings suggested that the @entity5 had been present much longer. One @entity1 was a 10-year-old female with a @entity808 filling the anterior and posterior triangles of the left side of her neck and extending superiorly to the base of the skull. The @entity5 intimately involved the vagus, spinal accessory, and hypoglossal nerves. The other @entity1 was a 12-year-old female with a nasal @entity5 filling the right naris and nasopharynx. Our management of these @entity1 is discussed.
