Lichen planus is a chronic inflammatory condition affecting skin and mucous membranes, characterized by purple polygonal papules.
Recognition of Lichen Planus's full clinical spectrum improves diagnostic accuracy and therapeutic response.
Epidemiology and Clinical Significance
The prevalence and incidence of Lichen Planus have been well-characterized through population-based studies.
- Factor 1: T-cell mediated autoimmune response
- Factor 2: Possible viral triggers (hepatitis C)
- Factor 3: Drug-induced variants (thiazides, ACE inhibitors, NSAIDs)
- Factor 4: Graft-versus-host disease
- Factor 5: Genetic predisposition
Causes and Risk Factors
Lichen Planus develops through dysregulation of normal skin homeostatic mechanisms.
- Purple, polygonal, pruritic papules and plaques
- Wickham's striae (white lines) on lesion surface
- Typically on wrists, ankles, genitals, oral mucosa
- Lesions may be painful, especially oral
- Post-inflammatory hyperpigmentation common
Pathophysiology and Disease Mechanisms
Lichen Planus develops through dysregulation of normal skin homeostatic mechanisms.
- Topical corticosteroids

- Phototherapy (UVB, PUVA, excimer laser)
- Intralesional corticosteroids
- Systemic corticosteroids
- Systemic retinoids
- Immunosuppressive agents for resistant cases
