Tinea Versicolor: These are commonly known as sunspots. However they are not created by the sun they are created by fungus tinea versicolor in which they can be white with no pigmentation to a pinkish red coloration circular in nature and they can conglomerate. Seek the advice of your dermatologist as there are shampoos and oral medications to combat this condition.
