01

A distinct pattern

The patches remain within a regional distribution and may spread more quickly during an initial active phase before becoming stable.

02

Why classification matters

Treatment response and the role of specialised procedures can differ from non-segmental vitiligo. Stability must be documented carefully before any surgical option is considered.
