Case Report: A Case of Type 1 Leprosy Reaction and Dapsone Hypersensitivity Syndrome Complicating the Clinical Course of Multibacillary Leprosy.

Type 1 reactions, characterized by increasing lesion erythema, pain, and nerve damage, commonly complicate leprosy. Dapsone hypersensitivity syndrome (DHS) is a potentially fatal reaction occurring 6-8 weeks into dapsone therapy. We present a case of intercurrent Type 1 reaction and DHS in a multibacillary leprosy patient recently started on multidrug treatment.
