A case of neurofibromatosis type1 with coexisting borderline tuberculoid leprosy

Leprosy and neurofibromatosis are different entities. both diseases present with nerve enlargement and skin lesions but the coexistence is rare. nodules of neurofibromatosis may be mistaken for that of lepromatous leprosy and vice versa. their simultaneous occurrence in same person may lead to diagnostic dilemma. we report a case which was at first mistaken as lepromatous leprosy. but proper history and examination aided by slit skin smear and skin biopsy for histopathological examination helped to reach the appropriate diagnosis of borderline tuberculoid leprosy associated with neurofibromatosis.
