Abstract

Linear IgA bullous dermatosis (LABD) is a rare autoimmune blistering disease that may be triggered by some diseases and medications. For the latter one, non-steroidal anti-inflammatory drugs (NSAIDs) have been identified as one of the potential causative agents to develop LABD. Here, a rare case of drug-induced LABD is introduced. A 13-month-old Iranian boy presented with a history of generalized blisters, displaying the classic “string of pearls” sign who was eventually diagnosed as a case of LABD. In his admission, he was diagnosed whit Mucocutaneous lymph node syndrome and treated with aspirin. Some features like appearing the characteristic lesions one week following the administration of aspirin, rapid clearance of lesions after the withdrawal of the drug, and reappearance of new lesions after readministration of aspirin were highly suggestive of aspirin-induced LABD. To establish the diagnosis, we used the “Naranjo probability score” which determined the probable causative role of aspirin. The diagnosis was confirmed by showing the positive IgA deposition in the basement membrane zone in a direct immunofluorescence study of the skin biopsy. The child was treated with dapsone with dramatical response to the drug. Copyright© October 2020, Iran J Allergy Asthma Immunol. All rights reserved.
