Linear IgA bullous dermatosis of childhood: Retrospective single‐center cohort

Abstract Linear IgA bullous dermatosis (LABD) is a rare autoimmune blistering disorder impacting children and adults. In this single‐center retrospective chart review of pediatric patients with LABD at a large tertiary referral center, we report the unifying and unique clinical features of 10 pediatric patients. Patients typically presented with the “cluster of jewels” sign ( n = 6; 60%), mucous membrane involvement ( n = 5; 50%) and had a mean disease duration of 38 months; six patients (60%) required inpatient admission for management of their skin disease, including all five patients who had mucous membrane involvement. Our findings suggest that pediatric LABD may be a disease with high morbidity and may be associated with severe complications when mucous membranes are involved.
