Co-localization of dermatophytosis with bt hansen in a child: A paradox

Abstract

Co-localization of fungal infections in preexisting BT Hansen's patches is rare. Previously, co-localization of dermatophytic infection with BT Hansen has never been reported. Pathologically, it is a paradox, because tuberculoid leprosy has an increased expression of Langerhans cells and dendritic cell, which are the primary mediators of first-line cutaneous mediators of immunity. Since superficial fungal infections such as pityriasis versicolor and tinea favor skin appendages, it may explain why such co-localization is not seen even when both disease entities, tinea and Hansen, are highly prevalent in certain regions of India.
