To the Editor: Neutrophils trapped in glomerular and paratubular capillaries of two human renal allograft biopsies showed the presence of unusual inclusions in the cytoplasm (Fig. 1, arrow) and rarely in the nuclei. The inclusions measured up to 1.6 μm by 0.1 μm, were not membrane bound, and had mostly a fibrillary substructure without any periodic banding. In addition, the neutrophils revealed degenerated mitochondria and an increase in cytoplasmic glycogen (Fig. 1, G). We are not aware of any previous report dealing with such inclusions. Linkns et al.
