Dapsone hypersensitivity is a form of drug allergic reaction involving multiple organs. This article reports the case of a man who experienced dapsone hypersensitivity after undergoing treatment for multibacillary leprosy with the dapsone regimen. The patient was diagnosed with dapsone hypersensitivity based on the presence of a skin eruption in the form of erythroderma and involvement of various internal organs.
