Table 2.

Systematic classification of colorectal lesions (eCLE based).

General architecture Cytonuclear features
Normal mucosa Regular (uniform) architecture of surface and glandular epithelium Epithelial cells are uniformly lined up along the basement membrane
Regular “honey-comb” appearance of vascular pattern Normal cell polarity of surface and glandular epithelium, normal aspect of mucin-producing goblet cells
Nonadenomatous polyps Slightly disturbed architecture: enlarged, branch-like, elongated crypts Epithelial cells are morphologically normal, preserved cell polarity
Increased number of cells in the crypts Depletion of goblet cells
Mild alterations of vascular pattern
Inflammatory infiltrate of lamina propria, decreased crypt/stroma ratio
Adenomatous polyps Disturbed architecture: mild irregularity of the crypts, eventual villous transformation, increased crypt/stroma ratio, crypt destruction Incomplete to lack of epithelial surface maturation
Mild to moderate alterations of vascular pattern Slightly cytonuclear atypia
Islands of malignant cells
