The rash was initially noticed on his groin and then spread to his hands, feet and mucosal surfaces. Laboratory tests were unremarkable, including an extensive infection aetiology work-up. Punch biopsies were obtained of a fresh lesion and were stained with H&amp;E and sent for direct immunofluorescence. Light microscopy and immunofluorescence study demonstrated a subepidermal blister with predominant neutrophilic infiltrates and a linear band of IgA at the dermoepidermal junction, respectively. The patient was diagnosed with linear IgA bullous dermatosis and was subsequently treated with 0.5\u2009mg\/kg of prednisone daily following previous case reports. At 1-week follow-up as an outpatient, the bullae became crusted, and the rash was nearly completely regressed.<\/jats:p>","DOI":"10.1136\/bcr-2021-242237","type":"journal-article","created":{"date-parts":[[2021,5,12]],"date-time":"2021-05-12T13:15:54Z","timestamp":1620825354000},"page":"e242237","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Idiopathic linear IgA bullous dermatosis treated with prednisone"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9782-9901","authenticated-orcid":false,"given":"Christopher Cantoria","family":"Garces","sequence":"first","affiliation":[{"name":"Department of Medicine, Michigan State University College of Human Medicine, Lansing, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M Fahad","family":"Salam","sequence":"additional","affiliation":[{"name":"Department of Medicine, Michigan State University College of Human Medicine, Lansing, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brian","family":"Nohomovich","sequence":"additional","affiliation":[{"name":"Michigan State University College of Osteopathic Medicine, East Lansing, Michigan, USA"},{"name":"Department of Microbiology and Molecular Genetics, Michigan State University College of Natural Science, East Lansing, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Merryl Treasa","family":"Varghese","sequence":"additional","affiliation":[{"name":"Department of Medicine, Michigan State University College of Human Medicine, Lansing, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2021,5,12]]},"reference":[{"key":"2025082708054436000_14.5.e242237.1","doi-asserted-by":"crossref","first-page":"508","DOI":"10.2340\/00015555-3154","article-title":"Drug-Induced linear IgA bullous dermatosis: a case report and review of the literature","volume":"99","author":"Lammer","year":"2019","journal-title":"Acta Derm Venereol"},{"key":"2025082708054436000_14.5.e242237.2","unstructured":"Bernett CN , Fong M , Rosario-Collazo JA .
