One or more macules in one area but not clearly in a segmental distribution.
In general terms Focal Vitiligo is localized to a single area. If the patient has a single patch on hand, face or leg with no other occurrences of disease on other body parts.
Focal vitiligo if not active is generally more suited for localized treatments. The first option would be a topical medicine and if it does not work or is unacceptable due to other reasons, surgery and tattooing may be considered.
