Malassezia is something that exists naturally on the skin, and tinea versicolor is an overgrowth of this yeast. Malassezia is also the cause for other skin conditions like dandruff and psoriasis. And while it can't be spread by skin-on-skin contact (meaning it's not contagious), it's hard to determine just what causes tinea versicolor, says Schultz.

Furthermore, the mycelial stage can be induced in vitro by the addition of cholesterol and cholesterol esters to the appropriate medium. Because the organism more rapidly colonizes humans during puberty when skin lipids are increased more than that of adolescent levels and tinea versicolor is manifested in sebum-rich areas (eg, chest, back), individual variations in skin surface lipids are hypothesized to play a major role in disease pathogenesis. However, patients with tinea versicolor and control subjects do not demonstrate any quantitative or qualitative differences in skin surface lipids. Skin surface lipids are significant for the normal presence of M furfur on human skin, but they probably play little role in the pathogenesis of tinea versicolor. Show details Patients need to realize that tinea versicolor is caused by a fungus that is normally present on the skin surface; thus, it is not considered a contagious disease. Sequelae from the disease are not permanent, and any pigmentary alterations resolve entirely 1-2 months after treatment is initiated. Treatment is needed to remedy the condition and for prophylaxis to prevent recurrences. Vigorous exercise an hour after taking the medication may help sweat it onto the skin surface, where it can effectively eradicate the fungus. Bathing should be avoided for a few hours. A few days' treatment will clear many cases of pityriasis long term, or at least for several months. tinea fungus | tinea versicolor selsun blue treatment tinea fungus | versicolor skin tinea fungus | white spots on skin from sun fungus
