Onychomycosis is a fungal infection of the toenails or fingernails that may involve any component of the nail unit, including the matrix, bed, or plate. Onychomycosis (also known as dermatophytic onychomycosis or tinea unguium) is a fungal infection of the nail.It is the most common disease of the nails and constitutes about half of all nail abnormalities.
Overview of Onychomycosis. Onychomycosis is a fungal infection that causes fingernails or toenails to thicken, discolor, disfigure, and split. If the problem is caused by a bacterium, the condition is called paronychia. The nails of people with onychomycosis are initially a cosmetic concern Onychomycosis is a fungal infection of the nails that causes discoloration, thickening, and separation from the nail bed. Onychomycosis occurs in 10% of the general population, 20% of persons older than 60 years, and 50% of those older than 70 years. Despite treatment, the recurrence rate of onychomycosis is 10% to 50% as a result of reinfection or lack of mycotic cure. Onychomycosis is a fungal infection of the fingernails or toenails that causes discoloration, thickening, and separation from the nail bed. 1 Onychomycosis is a type of nail infection caused by pathogenic fungi. 2  Approximately half of nail conditions are onychomycosis, making it the most common nail disorder. 3  Both fingernails and toenails can develop fungal infections, but toenails are more commonly affected. Onychomycosis is an infection of the nails caused by a fungus. Symptoms of the infection will vary depending on the type of fungus involved, but thickened nails and yellow discoloration are common. Onychomycosis (OM) refers to a fungal infection that affects the toenails or the fingernails. Onychomycosis may involve any component of the nail unit, including the nail matrix, nail bed, or nail plate. Practice Essentials. Onychomycosis is a fungal infection of the toenails or fingernails that may involve any component of the nail unit, including the matrix, bed, or plate. Onychomycosis can cause pain, discomfort, and disfigurement and may produce serious physical and occupational limitations, as well as reducing quality of lif Onychomycosis (also known as dermatophytic onychomycosis or tinea unguium) is a fungal infection of the nail. It is the most common disease of the nails and constitutes about half of all nail abnormalities. 1 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 (tinea unguium) is a fungal infection of the nail bed, matrix or plate. Toenails are affected more often than finger-nails. 1, 2 Onychomycosis accounts for one third of integumentary fungal infections and one half of all nail disease. 1 Tinea unguium occurs primarily in adults, most commonly after 60 years of age. The incidence of this infection is probably much higher than the reported 2 to 14 percent. The most common form of tinea unguium is distal subungual onychomycosis, which can also be distal and lateral (Figures 1 and 2) . Distal subungual onychomycosis may develop in the toenails, fingernails or both. Fungal Nail Infection (Onychomycosis) Overview. Fungal infection of the toenails or fingernails is caused by a fungal microbe that invades the nail bed. Fungal nail infection is also termed onychomycosis and tinea unguium. Fungal nail infection causes fingernails or toenails to thicken, discolor, disfigure, and split. At first, onychomycosis appears to be only a cosmetic concern. Without treatment, however, the toenails can become so thick that they press against the inside of the shoes, causing pressure, irritation, and pain. White superficial onychomycosis accounts for only 10 percent of onychomycosis cases. 3 The toenails are usually affected (Figure 4) . White superficial onychomycosis is caused by certain fungi that directly invade the superficial layers of the nail plate and form well-delineated opaque “white islands” on the plate. The most common form of tinea unguium is distal subungual onychomycosis, which can also be distal and lateral (Figures 1 and 2) . Distal subungual onychomycosis may develop in the toenails, fingernails or both.
