Superficial scrapes of skin examined underneath a microscope may reveal the presence of a fungus.This is done by utilizing a diagnostic method called KOH test, [6] wherein the skin scrapings are placed on a slide and immersed on a dropful of potassium hydroxide solution to dissolve the keratin on the skin scrappings thus leaving fungal elements such as hyphae, septate or yeast cells viewable.
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.

These fungal infections impair superficial layers of the skin, hair and nails. [1] Dermatomycosis is one of the most common types of infection worldwide. [2]
Trichophyton mentagrophytes is a species in the fungal genus Trichophyton. [1] It is one of three common fungi which cause ringworm in companion animals.It is also the second-most commonly isolated fungus causing tinea infections in humans, and the most common or one of the most common fungi that cause zoonotic skin disease.
Microsporum audouinii causes the infections Tinea capitis (scalp ringworm) and Tinea corporis. [2] These superficial dermal diseases are generally found in prepubescent children (starting at 6 months) and rarely affect adults. [3] There are a few reasons why children are more susceptible to M. audouinii.
Trichophyton is a genus of fungi, which includes the parasitic varieties that cause tinea, including athlete's foot, ringworm, jock itch, and similar infections of the nail, beard, skin and scalp. Trichophyton fungi are molds characterized by the development of both smooth-walled macro- and microconidia .
