Skin Yeast Infections – Tinea Versicolor and Pityriasis Versicolor
The skin yeast infections can be categorized into mainly two types – Pityriasis versicolor and Tinea Versicolor. The Pityriasis Versicolor is a common type of skin problem in which many discoloured patches may be observed on the back as well as on the chest. Sometimes, the infections may be even observed on the arms as well as trunks. The patches could be slightly itchy in nature and even appear in various colours such as coppery brown, pink or pale in comparison to the surrounding skin. However, the pale patches are observed commonly on the dark skinned person. This is called as Pityriasis Versicolor Alba and it is not so itchy in comparison to other coloured patches on the skin.
If a physician examines the infected skin by means of the Wood’s light, then the infected areas display a yellowish green fluorescence. The Pityriasis Versicolor is commonly observed in the hot and humid conditions. The people who sweat a lot are prone to get affected by this disease sooner. So, it may turn out to be the case of recurring infections, which become active during summer season.
Tinea versicolor is a type of skin infection, which is caused due to the yeast Malassezia furfur. The species is also called as Pityrosporum Ovale or Pityrosporum Orbiculare. This skin infection also causes various coloured patches on the skin. Hence, the name versicolor is coined to this category of skin yeast infections.
The patches are generally observed on the limbs and are very scaly in nature. The appearance of these patches is darker in comparison to the peripheral skin in a light skinned person, whereas in case of a dark skinned person, the patches are observed to be lighter in comparison to the surrounding skin.
After being exposed to the sunlight, the patches become more prominent. However, the Tinea Versicolor does not cause any permanent harm to the skin as such.
