The publisher is trying to point out that there are some inflammatory halos that can mimic koilocytosis, but no way these are nearly as big as those found characteristic in koilocytes. These halos mark degenerative changes.
Second, there are slight changes in size and shape of the nucleus; however, all cells are relatively uniform and within normal limits for N/C. LSIL nuclear sizes are within 2 to 3 times that of normal, and these all look less than that; probably 1.5X.
And thirdly, ASC-US occurs in mature superficial and intermediate cells. These cells come no where close to the size of them and you would obviously not call these high grade cells. Thus, taking you out of the malignancy category.
