A rare association of twenty-nail dystrophy with segmental vitiligo is described in two patients. Vitiligo preceded the nail dystrophy. ⋯ Longitudinal nail biopsy revealed a histological picture suggestive of eczematous changes and lichen planus respectively. Intramatrix injections of triamcinolone acetonide into the proximal and lateral nail folds were administered with considerable improvement.
