Oral lichenoid hypersensitivity reaction on exposure to tobacco product: a rare case report
The oral lichenoid lesion (OLL) is response that occurs on the oral mucosa. The OLL commonly include allergic response to the dental materials, drugs, and on graft-vs-host disease (GVHD). The prevalence of oral lichen planus is more with the female predilection. Oral lichenoid lesions develop as a type IV hypersensitivity reaction. Both of those entities are potential precancerous conditions; this adds to their clinical significance. Oral lichen planus and oral lichenoid reactions are two distinct diseases. They will be clinically similar but they need different etiologic factors.
