tinea unguium

It is the least common form of tinea unguium in healthy people, but is found more commonly when the patient is immunocompromised.

Tinea unguium affects the nails and athlete's foot (tinea pedis) affects the feet.

Oral 250 mg tablets are often prescribed for the treatment of onychomycosis of the toenail or fingernail due to the dermatophyte Tinea unguium.

Artificial nails increase the risk for tinea unguium as emery boards can carry infection, and water can collect under the artificial nail, creating a moist area for fungal growth.

Distal subungual onychomycosis is the most common form of tinea unguium, and is usually caused by Trichophyton rubrum, which invades the nail bed and the underside of the nail plate.

Onychomycosis, also known as tinea unguium, is a contagious infection of the nail caused by the same fungal organisms which cause ringworm of the skin (Trichophyton rubrum or T. mentagrophytes, rarely other trichophyton species or Epidermophyton floccosum ).
