Microscopic evaluation scheme of acute inflammation
Neutrophil Severity | |
Grade 0 | Scattered individual cells may be present in the wound but primarily intravascular/margin-ating or widely spaced within the wound |
Grade 1 | Viable/nondegenerate neutrophils as individual cells within the wound. If suppuration is present it does not coat the surface or span the length of the segment being graded |
Grade 2 | Variably thick suppurative inflammation that spans the length of the segment |
Grade 3 | Dense consistent thickness of suppurative inflammation that spans the length of the segment and neutrophils present within the wound bed below are in small clusters or individual |
Grade 4 | Large pools of suppurative exudate over the length of the segment with large numbers present in the underlying wound bed, mostly present in clusters. Abscess formation. |
Eosinophil Severity | Scored based on the number of foci of clustered eosinophils or numerous individual cells, when viewed at 10×. |
Grade 0 | Less than 10 foci |
Grade 1 | 11–20 foci |
Grade 2 | 21 to 30 foci |
Grade 3 | 31 to 40 foci |
Grade 4 | >40 foci |
