Classification of segmental vitiligo on the face: clues for prognosis

Abstract

Newly established patterns of facial SV may be valuable for certain aspects of prognosis, such as the likely degree and path of lesion spreading.

Classification of segmental vitiligo on the trunk

“…So far, a classification only for the face has been proposed. 4,5 Recognition of the different subtypes can provide further clues to the pathogenesis of SV. Furthermore, it can help to predict the possible susceptible areas of future distribution pathways for early developing SV lesions.…”

“…Type 1 is a rather small linear lesion at the midcentral ventral part of the upper trunk towards the chin. This is a fairly rare subtype that seems to be an extension of the type III SV pattern on the face proposed by Kim et al 4 It displays a meandering distribution on the left or right presternal area and can cross the midline of the trunk. Type 2 is located at the extension of the upper part of the shoulder.…”

A descriptive study to characterize segmental vitiligo

“…[14][15][16][17] Specific patterns have been described on the face, which do not follow dermatomal, blaschkoid, or acupuncture lines and have been revised recently. [18,19] The recognition of visual patterns is intrinsically subjective and difficult to automate or objectivize. [20] This is a particular problem because in some anatomical areas, such as the back and abdomen, there is considerable overlap between dermatomes and Blaschko lines.…”

Revised classification/nomenclature of vitiligo and related issues: the Vitiligo Global Issues Consensus Conference

“…On the basis of the observations of the Hann’s group, other collections/registers of cases should be obtained to reach an international consensus on segmentation (Kim et al, 2011). For NSV, the importance of the remaining melanocyte reservoir should be evaluated in addition to the descriptive classification.…”
