title: [Significance of ultrastructure of peripheral nerve tumors in pathological and differential diagnoses].
abstract: Biopsy material fixed with formalin in 10 cases of peripheral nerve tumors and 5 soft tissue tumors were studied with special reference to the significance of the ultrastructure of peripheral nerve tumors in histopathological and differential diagnosis. The results demonstrated that electron microscopic examination of formalin-fixed tissue may still reveal their ultrastructural characteristics. This is of certain practical value in pathological and differential diagnosis in some difficult peripheral nerve tumors.
