Lichen planus is a chronic inflammatory condition that can affect the skin and mucous membranes. Oral lichen planus (OLP) can manifest in a variety of forms including atrophic, bullous, erosive, plaque-like, and reticular.1 Wickham striae — slightly raised, fine, white or gray lines arranged in a lacy or web-like pattern — are often associated with OLP.2 These can present on the inside of the cheeks, tongue, and gums. The pathogenesis of OLP occurs as a consequence of autocytoxic T-cells that trigger apoptosis, or cell death, within the oral epithelium. Factors that may precipitate this include allergic-mediated reactions, hepatitis C infection, and autoimmune disorders.3

Diagnosis of OLP often can be made on clinical findings alone with bilateral interlacing white striae considered pathognomonic. The condition may be asymptomatic or associated with pain and burning. Approximately 25% of cases present without skin findings.4 No specific treatment for OLP exists; potent topical steroids often are used as first-line therapy to provide symptomatic relief.
