Oral-Genital Lichenoid Reaction: A Rare Hypersensitives to Drug, A Review

Background: Lichenoid reaction as the result of hypersensitivity from drug might be had similir clinical appearance to idiopathic lichen planus. Lichenoid drug reaction is termed as a condition of the oral cavity having an identifiable etiology, which is clinically and histologically similar to oral lichen planus and also manifest on genital. A number of drugs have been described as a causative factor of those reactive lesions. Objectives: The aim of this study is to finding mechanism of oral-genital lichenoid reaction caused by drugs. Problem Statement: Potential Pathway of Oral-genital lichenoid reaction caused by drugs. Discussion: Oral lichenoid lesions could be impact from medication and contact antigenic reaction. Clinical condition these two look similar to oral lichen planus, also its pathology. Studies of LDR caused by angiotensin-converting enzyme (ACE) inhibitors, antimalaria, antituberculosis, antitumor and non-steroidal anti-inflammatory drugs (NSAIDs) have been found. Conclusion: OLR is a disease condition with definite identifiable aetiology. Cell-mediated immune dysregulation has been associated with pathogenesis, explaining oral and genital manifestation.
