Oral lichen planus (OLP) is a chronic immune-mediated inflammatory disorder of the oral mucosa and is widely regarded as an oral potentially malignant disorder. Although the association between OLP and oral squamous cell carcinoma (OSCC) has been investigated in numerous studies, the magnitude of malignant transformation risk remains variable and is influenced by diagnostic criteria, follow-up duration, lesion subtype, epithelial dysplasia, tobacco and alcohol exposure, and geographic differences. This narrative review summarizes current evidence on the relationship between OLP and oral cancer risk using a structured descriptive search of PubMed, Scopus, and Web of Science. Relevant English-language studies addressing OLP, malignant transformation, and OSCC risk were reviewed and synthesized descriptively. The available evidence suggests that patients with OLP may have an increased risk of developing OSCC compared with the general population; however, reported transformation rates differ considerably among studies. Erosive or atrophic lesions, persistent ulceration, tongue involvement, epithelial dysplasia, and conventional carcinogenic exposures may further increase clinical concern. In addition to early diagnosis, long-term surveillance and biopsy of suspicious or non healing lesions are essential. Treatment should aim to control chronic inflammation while avoiding delayed recognition of dysplastic or malignant changes, particularly in patients receiving prolonged immunosuppressive or immunomodulatory therapy. Overall, OLP requires careful clinical monitoring because its malignant potential is context-dependent rather than uniform. Further well-designed studies with standardized diagnostic criteria and long-term follow-up are needed to clarify the biological mechanisms linking OLP to oral carcinogenesis and to improve risk stratification and prevention strategies.
