Clinical examination revealed well\u2010demarcated, bilateral white striations. Patient refused any type of biopsy, but after ruling out other potential causes, mesalazine was discontinued, resulting in complete symptom resolution and near\u2010total disappearance of oral lesions within 1 month, suggesting the diagnosis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A literature review was conducted using PubMed, Scopus, and Cochrane Library databases to identify similar cases and relevant information on mesalazine\u2010induced OLRs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>This case represents one of the few documented instances of mesalazine\u2010induced lichenoid reactions and a rare report of such involvement exclusively in the oral cavity, distinguishing it from previously reported cases, which involved concurrent cutaneous lesions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This report highlights the importance of considering mesalazine as a potential etiological factor in patients presenting with oral lichenoid lesions, particularly those with inflammatory bowel disease.
