Medical dermatology
Lichen Planus
An immune-mediated condition causing purple, itchy skin lesions and oral sores — diagnosed and managed by expert dermatologists in Miami.
Classic Features
- Skin: flat, purple, polygonal, pruritic papules — often on wrists, ankles, lower back
- Oral: reticular white patches (Wickham striae) or erosive lesions on gums and inner cheeks
- Nails: ridging, thinning, and pterygium formation
- Scalp (lichen planopilaris): follicular inflammation leading to scarring alopecia
Causes
The exact trigger is unknown, but T-cell-mediated immune attack on keratinocytes is central. Associations include hepatitis C virus infection, certain medications (thiazides, NSAIDs, antimalarials), and dental amalgam.
Treatment
- Topical: high-potency corticosteroids (clobetasol), tacrolimus for oral/genital lesions
- Intralesional: triamcinolone for hypertrophic variants
- Systemic: hydroxychloroquine, acitretin, cyclosporine, mycophenolate mofetil
- Phototherapy: narrowband UVB for widespread cutaneous disease
Monitoring
Erosive oral lichen planus carries a small risk (< 1%) of oral squamous cell carcinoma; regular follow-up is essential.
