Lichen Planus and Nail Involvement
This document provides information about Lichen Planus (LP), particularly its effects on nails (Nail Lichen Planus or NLP). Lichen planus is an inflammatory condition that can affect the skin, mouth, scalp, nails, and other areas of the body.
Considerations for Children
The text mentions studies and cases related to nail lichen planus in children, indicating that this condition can affect younger individuals. A 6-year-old boy is specifically mentioned with rough and brittle nails.
Symptoms and Characteristics
- Nail Lichen Planus (NLP) can cause thinning, longitudinal ridging, and distal splitting of the nail plate.
- Affected nails may become brittle or split, and have ridges running lengthwise.
- In some cases, a "sand-papered appearance" is present.
- Severe cases can lead to nail loss.
- Inflammation can be present.
- Dorsal pterygium (fusion of the nail plate to the nail bed) may occur.
- Itching and burning sensations are common symptoms.
Prevalence and Occurrence
- Nail involvement occurs in approximately 10 percent of reported lichen planus cases.
- Nail Lichen Planus can affect fingernails, toenails, or both.
- Trachyonychia (rough, opaque nails) is seen in about 10% of patients with nail lichen planus.
- Nail changes may occur even in the absence of skin findings.
Diagnosis and Treatment
- Diagnosis can be confirmed through nail biopsy.
- Treatment of nail lichen planus can be difficult, and an optimal therapy is lacking.
- Various medications and treatments may be recommended for lichen planus of the skin, hair, and nails.
- Topical Tacrolimus has been used successfully in some treatments.
Related Conditions
- Yellow nail syndrome and lichenoid reactions can have similar origins.
- Nail involvement in lichen striatus (LS) is uncommon and usually occurs with typical skin lesions.
