abstract
Background: Segmental vitiligo and generalized vitiligo are in general considered separate entities. However, clinico-epidemiological data on segmental vitiligo are scarce compared with those of generalized vitiligo. Objective: To analyse the clinical profile and distribution pattern of lesions in segmental vitiligo patients. Methods: Segmental vitiligo patients were examined and questioned in a prospective and retrospective setting. The distribution and extent of the lesions were evaluated using clinical photographs. Results: Different phenotypes of segmental vitiligo were found, including the unilateral segmental type (124 patients; group 1), the bilateral segmental type (three patients; group 2) and the mixed segmental and generalized type (14 patients; group 3). Furthermore, lesions were present with (10%) or without associated halo naevi. The age of onset of segmental vitiligo (median 14 years) was significantly different between the three subgroups (P = 0.028). Extensive involvement of segmental vitiligo lesions on trunk and extremities was significantly (P = 0.031) more observed in patients with a lower age of onset, while the generalized vitiligo lesions in the mixed vitiligo group were mostly very mild. Associated autoimmune diseases were reported in 11%, whereas a positive family history for vitiligo was present in 14.9% of patients. Lesions were not strictly dermatomal nor Blaschkolinear, although a typical recurring pattern could be observed. Conclusion: Our data provide clinical evidence that segmental vitiligo and generalized vitiligo are parts of the same disease spectrum and that segmental vitiligo could have a polygenetic background as well. Whether different aetiopathological mechanisms underlie the different clinical phenotypes of segmental vitiligo remain to be elucidated.
