Fibroblasts grown from one involved and 7 uninvolved skin sites of patients with systemic lupus erythematosus (SLE), 2 patients with rheumatoid arthritis (RA), and one normal patient were examined by light, fluorescent, and electron microscopy. All failed to show evidence of virus like particles or tubuloreticular structures previously observed in the endoplasmic reticulum of tissue from patients with SLE. Densely staining intracellular punctate bodies 250-500 Å in diameter were tentatively identified by differential cytochemical staining as glycogen granules. Cultures from normal, SLE, and RA patients showed identical susceptibility to infection with Newcastle disease virus.
