Vitiligo delimiting dermatophyte infection

Sir, Dermatophyte infection, a common superficial fungal disease is precipitated by many factors such as advanced age, collagen vascular disease, systemic corticosteroid therapy or Cushing's disease, hematologic malignancy, chronic mucocutaneous candidiasis, diabetes mellitus, atopy, underlying peripheral vascular disease, and disorders of keratinization. Absence of melanin may play a role in inflammatory reactions following sun exposure according to Baghestani et al., who have reported familial colocalization of lichen planus and vitiligo on sun-exposed areas where lichen planus began from depigmented areas and then extended to normal skin.
