Abstract
Background:
Lichen planus may rarely be localized to the nails.
Objective:
A case of ungual lichen planus is reported that was misdiagnosed as onychomycosis.
Methods:
A 52-year-old woman had progressive nail dystrophy for 13 months that was unresponsive to oral terbinafine. A nail biopsy was performed.
Results:
Histopathologic findings were consistent with lichen planus.
Conclusion:
Onychomycosis may be confused clinically with other causes of nail dystrophy. It is important to confirm the diagnosis of onychomycosis with appropriate laboratory or histologic analysis.
