title: A sarcoma of myofibroblasts: an ultrastructural study.
abstract: A low-grade spindle cell sarcoma was shown by electron microscopy to be composed of myofibroblasts. It is suggested that the occurrence of myofibroblasts in spindle cell sarcomas might be of prognostic significance and that a systematic study to elucidate this point would be a valuable exercise.
