Question 11

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

Answer 11

Erosive

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

only stays in epidermis

not into basal zone

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

Answer 12

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
