Dapsone-induced agranulocytosis is a rare adverse effect. There are va
rious reports of agranulocytosis in patients treated with dapsone for
malaria prophylaxis and other dermatological diseases. However, this a
dverse reaction in leprosy is not often encountered. We describe agran
ulocytosis in a young patient who was taking dapsone (100 mg) for bord
erline-tuberculoid leprosy in a rural environment.
