Oral lichen planus. A review.

Area of Science:

• Dermatology
• Immunology
• Oral Medicine

Background:

• Lichen planus is a prevalent inflammatory disorder impacting skin, mucous membranes, nails, and hair.
• Oral lichen planus (OLP) is frequently encountered in clinical practice, with the buccal mucosa, tongue, and gingiva being common sites of involvement.
• The exact cause of OLP remains unknown, though immunofluorescence studies suggest an immunopathogenesis.

Purpose of the Study:

• To provide an overview of oral lichen planus (OLP).
• To discuss the diagnostic and management challenges associated with OLP.
• To highlight the ongoing controversy regarding malignant transformation of OLP.

Main Methods:

• Review of existing literature on lichen planus and oral lichen planus.
• Analysis of proposed immunopathogenesis based on immunofluorescence studies.
• Discussion of clinical presentation and management strategies.

Main Results:

• Oral lichen planus is a common mucosal condition.
• The etiology of OLP is currently unknown.
• The potential for malignant transformation of OLP is a subject of ongoing debate.

Conclusions:

• Management of OLP presents significant challenges for both patients and clinicians.
• Treatment decisions for OLP must carefully weigh the risks and benefits of available options.
• Therapeutic approaches should be individualized based on the specific extent and severity of the disease.
