The main complication of tinea versicolor is the skin discoloration that persists for weeks after treatment because the melanocytes (skin color-producing cells) require time to recover and properly pigment the skin. There are no permanent complications of tinea versicolor. As an entirely surface infection/colonization, there is no concern for deeper invasion in patients with intact immune systems. Malassezia may be a factor in pityrosporum folliculitis and, in stem-cell-transplant patients, may be a cause of lung problems.

    Recurrence of the rash is common, though it won’t recur necessarily every year.

The sample then can be stuck directly onto a slide to be looked at with a microscope.
