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.
These investigations show that the Malassezia species causing most skin disease in humans, including the most common cause of dandruff and seborrhoeic dermatitis, is M. globosa (though M. restricta is also involved). [1] The skin rash of tinea versicolor (pityriasis versicolor) is also due to infection by this fungus.
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.
In occasional opportunistic infections of the trunk and other locations on humans, some species of Malassezia can cause hypopigmentation or hyperpigmentation. Allergy tests for these fungi are available. The skin rash of tinea versicolor (pityriasis versicolor) is also caused by an infection of this fungus. [10]
[3] [6] Superficial fungal infections include common tinea of the skin, such as tinea of the body, groin, hands, feet and beard, and yeast infections such as pityriasis versicolor. [7] Subcutaneous types include eumycetoma and chromoblastomycosis, which generally affect tissues in and beneath the skin.
But unlike the neat circles typical with other forms of ringworm, the tinea caused by this new fungal infection may be mistaken for lesions caused by eczema, which could cause people not to seek ...
[31] [33] Onychomycosis, a common infection caused by dermatophytes, is found with varying prevalence rates in many countries. [34] Tinea pedis + onychomycosis, Tinea corporis, Tinea capitis are the most common dermatophytosis found in humans across the world. [34] Tinea capitis has a greater prevalence in children. [31]
The population of early humans dwindled to around 1,280 individuals during a time of dramatic climate change and remained that small for about 117,000 years, the study said. ... did show that ...
