Background: Segmental vitiligo is a small but unique subset of vitiligo requiring due importance due to its lack of response to medical treatment but excellent response to surgical treatment. Characterization of the pattern of segmental vitiligo will also help to understand the pathogenesis of the disease. Aim: To characterize clinically the features of segmental vitiligo, a cross-sectional clinical study at dermatology outpatient department at AIIMS was carried out. Methods: Consecutive 188 patients were evaluated to characterize the clinical features of segmental vitiligo by detailed history, clinical examination, and photography. Frequency of each clinical feature was calculated. Results: Certain features such as early onset, initial progression of disease followed by stability, blaschkoid pattern, irregular margins, leucotrichia within and beyond the vitiligo lesion, and islands of pigmented macules within the vitiligo lesion were found to be characteristic of the disease. Conclusions: A combination of various features such as early onset of disease, blaschkoid pattern, irregular margins, leucotrichia, and islands of pigmented macules within the vitiligo lesion are helpful in diagnosis of the disease.
