De Novo Histoid Leprosy with Borderline Tuberculoid Leprosy: A Rare Association

ABSTRACT: Histoid leprosy is an uncommon variant of lepromatous leprosy characterized by unique histopathological findings and characteristic bacterial morphology. It occurs in patients relapsing after dapsone monotherapy, in the presence of dapsone resistance or at times de novo. Though it is commonly seen in lepromatous leprosy, very rarely it may be seen in borderline and indeterminate leprosy. We report here a case of de novo histoid leprosy with borderline tuberculoid leprosy because of its rarity.
