Co-Existence Between Psoriasis and Vitiligo: A Case Report

Dr. Vaibhav Mali

Abstract: Introduction: Vitiligo is a pigmentary dermatosis where destruction of epidermal melanocytes causes macular or patchy depigmentation of the skin. Psoriasis is a chronic systemic inflammatory disease that typically presents on the skin as erythematous plaques with silvery scales. Co-existence between these two conditions is possible due to shared genetic basis and common cellular immune pathway. Case Report: Here we report a case in which an elderly male, known case of vitiligo since 5 year, presented with progressive red elevated lesions over patch of vitiligo on left lower limb since 6 months. Cutaneous examination revealed few erythematous plaque present over depigmented patch on left lower limb associated with fine scaling. Skin biopsy with dermatoscopy was done. Discussion: This case report is providing evidence regarding psoriasis susceptibility in generalized vitiligo patients with help of dermoscopy and histopathology.
