Spheroidal filamentous inclusion body cells in von Recklinghausen's disease.
Cells with spheroidal filamentous cytoplasmic bodies, distinctive by both light and electron microscopy, were found in a neoplasm arising from the sciatic nerve of a patient with von Recklinghausen's disease. Tissue fixed with formalin and embedded in paraffin for three years was deparaffinized, reprocessed, and examined with the electron microscope. The morphology of the spheroidal body cells, the close resemblance to erythrophagocytosis, and the possible significance of the changes are discussed.
