Onychomycosis is a chronic fungal infection of the fingernail or toenail bed leading to brittle, discolored, and thickened nails. Onychomycosis is not just a cosmetic problem. Untreated...

Four types of onychomycosis are recognized based on the site and pattern of fungal invasion. Dermatophyte fungi are the predominant pathogens, but yeasts (especially Candida albicans) and nondermatophyte molds may also be implicated. Accurate diagnosis requires direct microscopy and fungal culture.

Onychomycosis may complicate other nail pathology such as trauma or psoriasis. Candida infection of the nail plate generally results from paronychia and starts near the nail fold (the cuticle ). The nail fold is swollen and red, lifted off the nail plate.

2024年5月15日 · Nail fungus is also called onychomycosis (on-ih-koh-my-KOH-sis). When fungus infects the areas between your toes and the skin of your feet, it's called athlete's foot (tinea pedis). Symptoms of nail fungus include a nail or nails that are: Nail fungus can affect fingernails, but it's more common in toenails.

2022年9月8日 · Dermatophytes, particularly Trichophyton rubrum, are the most common causes of onychomycosis. Yeast (eg, Candida albicans) and nondermatophyte molds can also cause onychomycosis. (See "Onychomycosis: Epidemiology, clinical features, and diagnosis".)

Candida albicans accounts for approximately 70% of onychomycosis caused by yeasts . Other Candida species include Candida tropicalis and Candida parapsilosis [12, 17, 28, 33-35]. Patients with chronic mucocutaneous candidiasis and immunodeficiency are more likely infected with the yeast organism, especially in the fingernails [11, 28, 33, 36, 37].

2023年5月10日 · There are 4 main kinds of fungal nail infection. Each looks slightly different: Distal or lateral subungual onychomycosis. This is the most common kind. It results from a fungus called a...

oloration, thickening, and separation from the nail bed. Onychomycosis occurs in 10% of the general population but is more com-mon in older adults; the prevalence is 20% in those older than 60...

Candidal onychomycosis, also known as fungal nail infection, occurs when a type of yeast called Candida infects the nails. Typically, this condition affects toenails more commonly than fingernails. The overgrowth of Candida on the nails leads to the development of onychomycosis.

Onychomycosis due to Candida (candidal onychomycosis) is increasingly found in individuals having defective immunity consequential to aging, diabetes mellitus, vascular diseases, HIV infection and drug therapies such as immunosuppressives and broad-spectrum antibiotics.
