Leprosy with neurofibromatosis--a diagnostic dilemma.

The coexistence of leprosy with neurofibromatosis is a rare finding and can pose a diagnostic dilemma. Neurofibromatosis coexisting with borderline tuberculoid leprosy has previously not been reported. We report such a case in a 13-year-old boy where biopsy of clinically uninvolved nerve revealed the presence of acid-fast bacilli. A careful diagnostic workup is needed in such cases to ensure proper treatment. Both disorders affect Schwann cells and their relationship merits further consideration.
