title: Nail dystrophy in psoriatic arthritis presenting as nail onychomycosis: a case report.
abstract: Dystrophic nail changes without a skin lesion is a rare form of psoriasis. We describe a patient that presented with a chronic nail onychomycosis and a destructive thumb interphalangeal joint which was initially considered as onychomycotic joint infection, and was later diagnosed as having dystrophic nail changes in psoriatic arthritis and coexistent onychomycosis. The nail changes were completely normalized after methotrexate treatment.
