Tinea versicolor (also pityriasis versicolor) is a condition characterized by a skin eruption on the trunk and proximal extremities. [1] The majority of tinea versicolor is caused by the fungus Malassezia globosa, although Malassezia furfur is responsible for a small number of cases. [2] [3] These yeasts are normally found on the human skin and ...
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. [3] [6] Superficial fungal infections include common tinea of the skin, such as tinea of the body, groin, hands, feet and beard, and yeast ...

Dermatophytosis. Dermatophytosis, also known as tinea and ringworm, is a fungal infection of the skin [2] (a dermatomycosis ), that may affect skin, hair, and nails. [1] Typically it results in a red, itchy, scaly, circular rash. [1] Hair loss may occur in the area affected. [1] Symptoms begin four to fourteen days after exposure. [1]
Pityriasis rosea. Pityriasis rosea is a type of skin rash. [2] Classically, it begins with a single red and slightly scaly area known as a "herald patch". [2] This is then followed, days to weeks later, by an eruption of many smaller scaly spots; pinkish with a red edge in people with light skin and greyish in darker skin. [4]
Tinea is often called "ringworm" because the rash is circular, with a ring-like appearance. It is sometimes equated with dermatophytosis, and, while most conditions identified as "tinea" are members of the imperfect fungi that make up the dermatophytes, conditions such as tinea nigra and tinea versicolor are not caused by dermatophytes.
Malassezia is a genus of fungi (specifically, a yeast ). Some species of Malassezia are found on the skin of animals, including humans. Because malassezia requires fat to grow, [3] it is most common in areas with many sebaceous glands —on the scalp, [4] face, and upper part of the body.
