Epithelia surrounded by poorly defined striae

Lichen planus

Severe erosive OLP


Thick layers of yellowish fibrin covers extensive ulcers

on the dorsum of the tongue

Lichen planus

Erosive OLP: Two extensive areas of shallow ulcerations on the dorsum of the tongue

covered with fibrin layers

Lichen planus
