Another example is cutaneous candidiasis. 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] In some populations, over 20% of people have a dermatomycosis, which is typically not severe enough to prompt them to visit a clinic.
Tinea versicolor (also known as dermatomycosis furfuracea, pityriasis versicolor, and tinea flava) [2] is a condition characterized by a skin eruption on the trunk and proximal extremities, hypopigmentation macule in area of sun induced pigmentation. During the winter the pigment becomes reddish brown.
Dermatophytosis, also known as tinea and ringworm, is a fungal infection of the skin [2] (a dermatomycosis), that may affect skin, hair, and nails.

Children from ages 3–7 are most commonly infected with tinea capitis. [3] Trichophyton tonsurans is the most common cause of out breaks of tinea capitis in children, and is the main cause of endothrix (inside hair) infections. Trichophyton rubrum is also a very common cause of favus, a form of tinea capitis in which crusts are seen on the scalp.
It may have a variety of appearances; most easily identifiable are the enlarging raised red rings with a central area of clearing (). [3]The same appearances of ringworm may also occur on the scalp (tinea capitis), beard area (tinea barbae) or the groin (tinea cruris, known as jock itch or dhobi itch).
Microsporum canis has been identified as a causal agent of a ringworm infection in pets, tinea capitis and tinea corporis in humans, children in particular. [ 2 ] [ 3 ] [ 5 ] [ 14 ] [ 15 ] Microsporum canis is among the most common dermatophytes associated with tinea capitis and tinea corporis.
Tinea nigra, also known as superficial phaeohyphomycosis and Tinea nigra palmaris et plantaris, [2] is a superficial fungal infection, a type of phaeohyphomycosis rather than a tinea, that causes usually a single 1–5 cm dark brown-black, non-scaly, flat, painless patch on the palms of the hands and the soles of the feet of healthy people.
