A biopsy is useful in identifying histological features that help differentiate OLP from these conditions, except of the histollogy identical lichenoid reaction lesion, and frictonal keratosis and morsicatio buccarum which can be diagnosed clinically without histo-pathlogical examination.
A biopsy is useful in identifying histological features that help differentiate OLP from these conditions, except of the histollogy identical lichenoid reaction lesion (including lichenoid reaction of graft-versus-host disease). Frictional keratosis and morsicatio buccarum can and should be diagnosed clinically without histo-pathlogical examination.
