Q

superficial, partial loss of surface epithelium; may arise secondarily from rupture of bulla (blister)

Superficial loss of the surface epithelium
 Heals without scarring
 Usually looks red clinically

A

Erosive

Superficial loss of the surface epithelium
 Heals without scarring
 Usually looks red clinically

only stays in epidermis

not into basal zone

Q

loss of surface epithelium down to the connective tissue, often appears depressed

A

Ulcerated

Complete loss of the surface epithelium
 Involves lamina propria and possibly the deeper
submucosa of the connective tissue
 Usually looks white/yellow intraorally due to
fibrinous pseudomembrane covering ulcer bed
