Published on: 

Take our latest 5-question quiz based on the recommended strategies of laboratory-based diagnosis of epidermolysis bullosa.

The week leading up to and during the American Academy of Dermatology (AAD) 2024 Annual Meeting, as well as the Society for Pediatric Dermatology (SPD) Pre-AAD meeting has been a viable moment to reflect on recent major advances in the treatment capability of rare skin diseases including epidermolysis bullosa (EB).

At a time when 2 agents—beremagene geperpavec (B-VEC; VYJUVEK) and birch triterpenes topical gel (Filsuvez)—recently received US Food and Drug Administration (FDA) and a third—pz-cel—is awaiting decision this year, dermatologists will have a suddenly robust armamentarium for the rare, blistering and potentially fatal condition.

All the same, greater emphasis must be put on timely and adequate diagnostic practices in order to optimize the benefit of new treatments. This latest HCPLive Clinical Quiz tests readers’ knowledge on the diagnosis of EB, based on recommendations published in The British Journal of Dermatology in 2019.
