Tinea versicolor is a common skin condition due to overgrowth of skin surface yeast. This overgrowth results in uneven skin color and scaling that can be unsightly and sometimes itchy. The yeast normally lives in the pores of the skin and thrives in oily areas such as the neck, upper chest and back.
Tinea Versicolor FAQ
Tinea versicolor has small, scaly white-to-pink or tan-to-dark spots, which can be scattered over the upper arms, chest and back. They may sometimes appear on the neck and the face. On light skin, tinea versicolor may be faint or can appear as tan-to-pink spots, while on dark skin tinea versicolor may be light or dark. The fungus grows slowly and prevents the skin from tanning normally. As the rest of the skin tans in the sun, the pale spots, which are affected by the yeast, become more noticeable, especially on dark skin.
Tinea versicolor usually produces few symptoms. Occasionally, there is some slight itching that is more intense when a person gets hot.
Although the light- or dark-colored spots can resemble other skin conditions, a dermatologist can easily recognize tinea versicolor. In most cases, the appearance of the skin is diagnostic, but a simple examination of the fine scales scraped from the skin can confirm the diagnosis. Scales are lightly scraped onto a slide and examined under a microscope for the presence of the yeast. A special light may help to make the diagnosis by showing a yellow-green color where the skin is affected.
Tinea versicolor is treated with topical or oral medications. Topical treatment includes special cleansers, including some shampoos, creams or lotions applied directly to the skin.
Several oral medications have been used successfully to treat tinea versicolor. Because of possible side effects, or interactions with other medications, your dermatologist should supervise the use of these prescription medicines. After any form of treatment, the uneven color of the skin may remain several months after the yeast has been eliminated until the skin re-pigments normally.
Tinea versicolor may recur. Special cleansers may decrease episodes when used once or twice a month, especially during warm humid months of the year.
Each patient is treated by the dermatologist 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.
