Onychomycosis due to dermatophyte

Onychomycosis due to dermatophytes, also termed tinea unguium, is a fungal infection of the nail apparatus caused specifically by dermatophytic molds, predominantly *Trichophyton rubrum* and *Trichophyton mentagrophytes* This enzymatic invasion produces hallmark clinical features including subungual hyperkeratosis, yellow-to-brownish nail discoloration, onycholysis, and progressive nail plate brittleness or dystrophic thickening

Pathophysiologically, the fungi produce keratinases that digest the keratinized structures of the nail plate, nail bed, and hyponychium
