ICD-10 code: B35. 1 Tinea unguium | gesund.bund.de.
Onychomycosis (tinea unguium) is a fungal infection of the nail bed, matrix or plate. Toenails are affected more often than finger-nails. Onychomycosis accounts for one third of integumentary fungal infections and one half of all nail disease.
Onychomycosis, also known as tinea unguium, is a fungal infection of the nail. Symptoms may include white or yellow nail discoloration, thickening of the nail, and separation of the nail from the nail bed. Toenails or fingernails may be affected, but it is more common for toenails.
Diagnosis is primarily based upon KOH examination, culture and histopathological examinations of nail clippings and nail biopsy. Adequate and appropriate sample collection is vital to pinpoint the exact etiological fungus. Various improvisations have been adopted to improve the fungal isolation.
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.
Most cutaneous infections are the work of the homogeneous group of keratinophilic fungi known as dermatophytes. The dermatophyte Trichophyton rubrum is the major cause of tinea pedis and onychomycosis (8).
Summary. Tinea pedis is the infection of the skin of the foot with fungus and must be distinguished from other causes of scaling rashes of the hands and feet. Tinea unguium (onychomycosis) is the infection of the nail unit with fungus where the fungus may be in one or more of the component structures of the nail unit.
PresentationSymptoms. asymptomatic.Physical exam. distal and lateral or proximal subungual onychomycosis. thickened with white, yellow, or brown discoloration. thickened nail may separate from the nail bed. most commonly affects first or fifth nail. superficial white onychomycosis. white discoloration of nail plate.
Onychomycosis is caused by 3 main classes of fungi: dermatophytes, yeasts, and nondermatophyte molds. Dermatophytes are by far the most common cause of onychomycosis. Two major pathogens are responsible for approximately 90% of all onychomycosis cases.
Total dystrophic onychomycosis or severe onychomycosis refers to the most advanced form of any of the subtypes. This form of onychomycosis is a later stage of the chronic subungual dermatophyte infection that may take 10 to 15 years to develop.
Onychomycosis is an infection of the nail caused by fungi such as dermatophytes, non-dermatophyte moulds and yeasts (mainly Candida species). Of these 80% of the toenail infections are caused by dermatophytes (Trichophyton rubrum).
The fungus that causes onychomycosis may be of several types, including yeasts, dermatophytes or molds. In almost all the cases, onychomycosis is caused by dermatophytes, which affect not only the nails but also the skin and the hair, that are tissues containing keratin.
