Tinea Versicolor (Pityriasis Versicolor)
Tinea versicolor (TV), also known as pityriasis versicolor, is a superficial fungal infection of the skin. Normally it is caused by lipophilic fungi of the genus Malassezia. The fungal species inducing TV are M. globosa, M. sympodialis, and M. furfur. Clinical signs are very clear since different fungi species develop filaments and induce the peculiar stratum corneum damage, characterized by depigmentation and inflammation. TV is one of the commonest skin diseases with a wide geographical range. This infection may occur in healthy individuals and in immunocompromised patients, although it is not a marker of human immunodeficiency virus (HIV) infection.
