Fungal infection, also known as mycosis, is a disease caused by fungi. [ 5 ] [ 13 ] Different types are traditionally divided according to the part of the body affected; superficial, subcutaneous , and systemic.
Tinea corporis (also known as "ringworm", [2] tinea circinata, [11] and tinea glabrosa [2]) is a superficial fungal infection (dermatophytosis) of the arms and legs, especially on glabrous skin; however, it may occur on any part of the body, it present as annular, marginated plaque with thin scale and clear center.
Worldwide, superficial fungal infections caused by dermatophytes are estimated to infect around 20-25% of the population and it is thought that dermatophytes infect 10-15% of the population during their lifetime. [31] [32] The highest incidence of superficial mycoses result from dermatophytoses which are most prevalent in tropical regions.
Micrograph of a superficial dermatomycosis. The fungal organisms are the dark staining, thick, quasi-linear objects below with skin surface. Vulvar biopsy. GMS stain. Specialty: Infectious diseases Symptoms: These fungal infections impair superficial layers of the skin, hair and nails.
The epidermis is the most superficial layer of skin, a squamous epithelium with several strata: the stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale. [8] Nourishment is provided to these layers by diffusion from the dermis since the epidermis is without direct blood supply.
Some examples of common fungal skin infections include: Dermatophytosis , also known as ringworm, is a superficial fungal infection of the skin caused by several different species of fungi. The fungal genera which cause skin infections in humans include Trichophyton , Epidermophyton , and Microsporum . [ 21 ]
Mycosis-related cutaneous conditions are caused by fungi or yeasts, and may present as either a superficial or deep infection of the skin. Pages in category "Mycosis ...
Infections by dermatophytes affect the superficial skin, hair, and nails are named using "tinea" followed by the Latin term for the area that is affected. [3] Manifestation of infection tends to involve erythema, induration, itching, and scaling. Dermatophytoses tend to occur in moist areas and skin folds. [8]
