Lichen Planus

Q: Is lichen planus contagious?

No. Lichen planus is an autoimmune condition — it is not caused by a bacteria or virus and cannot spread from person to person.

Q: Can lichen planus be cured?

Skin lichen planus often resolves within 1–2 years, though it can recur. Oral and nail lichen planus tends to be more chronic. Treatment controls symptoms and reduces flares but is not curative in all cases.

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.
