From: The evaluation of three treatment protocols using oral prednisone and oral meloxicam for therapy of canine idiopathic lymphoplasmacytic rhinitis: a pilot study

Parameter Description Score Final overall score of histopathology
Neutrophils Not present 0 (0–12)
Lymphocytes 100–200 cells per 3 fields- mild 1
Plasma cells 201–300 cells per 3 fields- moderate 2
Eosinophils > 300 cells per 3fields- severe 3
Total inflammation score (0–12) Mild (0–3) 1 0–2 (−) absent 3–5 (+) mild 6–9 (++) moderate 9 (+++) severe
Moderate (4–6) 2
Severe > 7 3
Epithelial and goblet cell hyperplasia Mild (focal thickened epithelium) 1
Moderate (multifocal thickened epithelium) 2
Severe (diffuse thickened epithelium) 3
Mucosal oedema Mild (present in less than 20% of 3 random fields) 1
Moderate (20–40% of 3 random fields) 2
Severe (> 40% of 3 random fields) 3
