Hot, humid weather and lots of sweating can create a warm, moist environment for the yeast to overgrow. This is why the infection is more common in tropical countries. The yeast also likes an oily environment, so oily skin can play a part (and of course, teens and young adults can have oily skin).

Acidic bleach from the growing yeast causes areas of skin to be a different color than the skin around them. These can be individual spots or patches. Specific signs and symptoms of the infection include:

Call for Abstracts September 13, 2018  Vol. 379  No. 11 Full lecture Tinea versicolor is caused by the dimorphic, lipophilic organisms in the genus Malassezia, formerly known as Pityrosporum. Fourteen species are recognized within this classification of yeasts, of which Malassezia globosa, Malassezia sympodialis, and Malassezia furfur are the predominant species isolated in tinea versicolor. [1, 2, 3, 4, 5, 6, 7, 8] Malassezia is extremely difficult to propagate in laboratory culture and is culturable only in media enriched with C12- to C14-sized fatty acids. Malassezia is naturally found on the skin surfaces of many animals, including humans. Indeed, it can be isolated in 18% of infants and 90-100% of adults. [9]

    Each patient is treated by your Water’s Edge Dermatology practitioner according to the severity and location of the disease, the climate, and the desire of the patient. It’s important to remember that the yeast is easy to kill, but it can take weeks or months for the skin to regain its normal color.

    This skin disease commonly affects adolescents and young adults, especially in warm and humid climates. The yeast is thought to feed on skin oils (lipids), as well as dead skin cells. Infections are more common in people who have seborrheic dermatitis, dandruff, and hyperhidrosis.[4]

    Oral treatment for tinea versicolor has the advantage of simplicity. Two doses of fluconazole (Diflucan) or itraconazole (Sporanox) prescribed by your doctor can clear most cases of this infection. Some common medications such as alprazolam (Xanax) and montelukast (Singulair) may interact with fluconazole, so your doctor will need to know what other medications are being taken before treating tinea versicolor orally.

    Evidence has been accumulating to suggest that amino acids, rather than lipids, are critical for the appearance of the diseased state. In vitro, the amino acid asparagine stimulates the growth of the organism, while another amino acid, glycine, induces hyphal formation. In vivo, the amino acid levels have been shown to be increased in the uninvolved skin of patients with tinea versicolor in two separate studies.

    The term pityriasis is used to describe skin conditions in which the scale appears similar to bran. The multiple colours of pityriasis versicolor give rise to the second part of the name, versicolor. Pityriasis versicolor is sometimes called tinea versicolor, although the term tinea should strictly be used for dermatophyte fungus infections.
