versicolor (also known as pityriasis versicolor) is a fungal infection that
causes a skin rash. The rash is formed by many small spots that typically
appear on the oily parts of the upper body, usually on the chest, back, and
upper arms. The spots are flat and may be white, pink, red, tan, or brown. Each
person's spots are usually the same color, either lighter or darker than the
rest of the skin.
