Histoid leprosy is a rare form of multibacillary leprosy with distinct clinical and histopathological features. It is a variant of lepromatous leprosy. It occurs in lepromatous patients, who relapse after dapsone monotherapy, in the presence of dapsone resistance or at times 'de-novo'. We describe here a case of histoid leprosy, clinically mimicking neurofibromatosis.
