title: Fibrosarcoma: observations on the ultrastructure.
abstract: Ultrastructural observations on 60 fibrosarcomas are presented. Myofibroblastic differentiation was found in 33 tumors but usually in scattered cells. Diffuse aggregates of nonspecific intermediate filaments were present in a number of the tumors. Electron microscopy is useful to distinguish fibrosarcoma from other soft tissue sarcomas that it can resemble by routine light microscopy, and its value is enhanced when selected immunocytochemical procedures are also performed.
