Table 1. Microscopic characteristics of gastric epithelial dysplasia

1. Cellular atypia
- nuclear pleomorphism
- hyperchromasia
- nuclear stratification
- increased N/P ratio
- sometimes increased cytoplasmic basophilia
- loss of cellular and nuclear polarity
2. Abnormal differentiation
- lack or reduced numbers of goblet cells and Paneth cells in the metaplastic intestinal epithelium
- reduction, alteration or disappearance of secretory products from the gastric epithelium
3. Disorganized mucosal architecture
- irregularity of crypt structure
- back-to-back gland formation
- budding and branching of crypts
- intraluminal and surface papillary growth
