Clinical characteristics and treatment outcomes of linear IgA bullous dermatosis.

Linear immunoglobulin A (IgA) bullous dermatosis (LABD), also referred to as chronic bullous disease of childhood (CBDC), is characterized by the linear deposition of IgA antibodies within the dermal-epidermal junction. While dapsone is typically recommended, alternative modalities may be considered based on accessibility, severity, and prior response to therapy. This review aims to provide an updated overview of the clinical characteristics and treatment outcomes for LABD/CBDC.

Successful treatment of erosive lichen planus with Upadacitinib complicated by oral squamous cell carcinoma.

Erosive lichen planus is a chronic auto-inflammatory disease which affects the stratified squamous epithelia resulting in painful ulcerations of both the skin and mucosal surfaces, and has a known malignant potential. Management of erosive lichen planus has proven to be difficult; however, recent reports of treatment with Janus kinase inhibitors such as Upadacitinib, are encouraging. This report outlines the third reported case of erosive lichen planus to be successfully treated with Upadacitinib in a 70-year-old woman with treatment-resistant disease.
