Summary
Nail involvement in lichen sclerosus (LS) is rare but documented in two cases. This study highlights nail disease as a potential, though uncommon, manifestation of LS, distinct from lichen planus (LP).
Area of Science:
- Dermatology
- Pathology
Background:
- Lichen sclerosus (LS) predominantly affects anogenital skin (80% of cases).
- Extragenital LS typically involves the trunk, neck, axillae, and wrist flexures.
- Nail involvement is a rare presentation of LS.
Observation:
- This report details two cases of LS with nail involvement.
- In Case 1, LS was confined to the nail, confirmed by biopsy.
- In Case 2, nail changes were part of generalized LS affecting genital and extragenital sites.
Findings:
- Nail disease can be an isolated or systemic manifestation of lichen sclerosus.
- Histological confirmation is crucial for diagnosing LS of the nail.
- Distinguishing LS nail disease from other conditions like lichen planus (LP) is important.
Implications:
- Recognizing nail involvement expands the clinical spectrum of LS.
- Further research into the etiology of LS nail disease is warranted.
- This finding may aid in earlier diagnosis and management of LS.
