Oral lichenoid reaction on right buccal mucosa: A case report

Oral lichenoid reactions (OLRs) have been considered as variants of oral lichen planus (OLP) and can be regarded as a disease per se, or it can be considered as an exacerbation of a pre-existing OLP by the presence of medication or dental materials. OLRs represent a type IV hypersensitivity reaction and mostly affect the oral mucosa when comes in direct contact with drugs or dental materials. OLRs can cause functional difficulty and significant discomfort in the patients, and hence, oral physicians should be aware of such reactions, its etiology, site of occurrence, diagnosis, and management. Here, we report a case of OLR of the right buccal mucosa associated with the placement of a lozenge for sore throat in the region of lower buccal vestibule and mucosa. Healing of the lesion was noted following the disuse of lozenge in that area.
