Vitiligo

There are several diseases that are frequently misdiagnosed as vitiligo. These include pityriasis alba and tinea versicolor. Pityriasis alba is a common condition found in young people. It appears as white patches on the upper arms and sometimes the thighs. Close examination shows an indistinct border and fine surface scale.
