White spot on the body is vitiligo, right?

White spots on the body are not necessarily vitiligo. They may also be caused by tinea versicolor and pityriasis alba. Tinea versicolor is caused by fungal infection and requires antibacterial treatment. Pityriasis alba is caused by local skin depigmentation after skin inflammation. Whether it is vitiligo can be identified by Wood's lamp at the dermatology department.
