Tinea versicolor
open-in-new
<p>Tinea versicolor (also pityriasis versicolor) is a condition characterized by a skin eruption on the trunk and proximal extremities. The majority of tinea versicolor is caused by the fungus <i><a href="/facts/Malassezia_globosa/3uoNQqbL">Malassezia globosa</a></i>, although <i><a href="/facts/Malassezia_furfur/TqoSD8V1">Malassezia furfur</a></i> is responsible for a small number of cases. These <a href="/facts/Yeasts/eGD24nfI">yeasts</a> are normally found on the <a href="/facts/Human_skin/cfRXQwSs">human skin</a> and become troublesome only under certain conditions, such as a warm and humid environment, although the exact conditions that cause initiation of the disease process are poorly understood. </p><p>The condition pityriasis versicolor was first identified in 1846. Versicolor comes from the Latin <i><i>versāre</i></i> 'to turn' + <i>color</i>. </p><p>It is commonly referred to as Peter Elam's disease in many parts of South Asia. </p>
