Glomerulonephritis was observed in both NaCl + GVHD and iHg + GVHD mice as evidenced by glomerular enlargement, increased glomerular lobularity, mesangial hypercellularity, and membrane thickening, compared with control [F.sub.1] mice (Figure 3A-D).

All scattergrams including lobularity of 90 degrees and complexity of 10 degrees that showed the separation of polymorphonuclear cells from mononuclear cells were scrutinized carefully.

The tumor grew in monomorphic nests and sheets that were infiltrated by neutrophils and macrophages; the fragmented and necrotic nature of the biopsy made it difficult to assess for the presence or absence of lobularity. The tumor cells had distinct cell borders with no syncytial arrangement, and they exhibited scant cytoplasm, round to oval nuclei with irregular nuclear membranes, vesicular chromatin, prominent nucleoli, and frequent mitotic figures with apoptotic bodies in a necrotic background (Figure 1, A and B).

(64,68) In some cases, distinct accentuation of glomerular lobularity creating an appearance reminiscent of membranoproliferative glomerulonephritis is present, whereas in others, proliferative activity is not pronounced (Figure 27, A).

Microscopically on low power, chordomas show a distinct lobularity, with fibroblast-rich fibrous septae.
