Tinea versicolor also called pityriasis versicolor, is infection of the skin of the upper body round the shoulders and upper trunk with the fungus Malasezzia furfur. This fungus exists all around us, including on the skin. The fungus intervene with the normal tanning of the skin. This ensues in small areas which are lighter than surrounding skin. Tinea versicolor can result in patchy skin color. The typical lesion is a bland discoloration with a sharp border and fine scales. Pityriasis versicolor does not appear to preincline affected areas to sunburn even when it causes pale white marks.
Tinea versicolor is frequent year-round in the tropics and subtropics and is visible in the summer months in more temperate climates. The infection, that is most common in warm, sultry temperatures, usually affects the back, chest, neck or upper arms and can cause mild itching. It rarely targets the face. It occurs majorily in juvenescence and early adulthood, but it can happen at any time. People with oily skin, mainly teens and young adults, are more probably to get tinea versicolor.
Tinea versicolor is a benign skin disease which causes scaly macules or papules on the skin. Most people who get this rash are in pleasant health. Nevertheless, tinea versicolor is more likely to occur if you have a suppressed immune system, for instance, if you are taking a corticosteroid medication such as prednisone for another health problem. In African Americans, pigmentary variations are common with hypopigmentation (loss of color) or hyperpigmentation (increase in skin color).
Itching may be suffered. The patches are slightly reddish brown on very pale skin but they don't tan. Due to deficiency of any tanning, they look like white spots on darker or tanned skin. In hyperpigmented macules in tinea versicolor, the organism persuases an enlargement of melanosomes made by melanocytes at the basal layer of the epidermis. Tinea versicolor normally is less possibly to occur as you age, when the skin becomes less oily. Antifungal creams, lotions or shampoos can help cure tinea versicolor.
