Зображення 00624. Nail psoriasis mimicking proximal subungual onychomycosis

Nail psoriasis has variable clinical features. This clinical picture mimics proximal subungual onychomycosis. Negative mycology and spontaneous resolution of the lesions suggest a non-infectious origin of the lesions. In immunocompetent patients some cases caused by Fusarium, a non-dermatophyte mold, have been reported.
