Background:

Lichen planus is an inflammatory mucocutaneous disease characterized by pruritic, violaceous papules and plaques.
It can affect the skin, oral mucosa, genital mucosa, scalp, and nails, with potential for disfigurement and debilitation.
Oral lichen planus carries a risk of malignant transformation into squamous cell carcinoma.

Purpose of the Study:

To summarize the key features, potential causes, and management strategies for lichen planus.
To highlight the association between oral lichen planus and squamous cell carcinoma.
To outline treatment approaches based on disease localization and severity.

Main Methods:

Review of existing literature on lichen planus.
Analysis of etiological factors including medications and viral infections.

Summary of current therapeutic interventions.

Main Results:

Lichen planus presents with characteristic skin and mucosal lesions, often associated with severe pruritus.
Etiology can be idiopathic, medication-induced (e.g., NSAIDs, ACE inhibitors), or linked to Hepatitis C Virus (HCV) infection.
Treatment varies from potent topical steroids for localized disease to systemic steroids for generalized or severe cases.

Conclusions:

Lichen planus is a complex inflammatory condition with diverse clinical manifestations and potential complications.
Understanding its varied etiology is crucial for effective management and patient counseling.
Prompt and appropriate treatment, guided by disease severity and location, is essential to manage symptoms and prevent long-term sequelae.
