Acrodermatitis continua of Hallopeau is a sterile pustular dermatosis primarily of the digits. Often considered a type of pustular psoriasis, it may be difficult to diagnose and even more difficult to treat. Initial involvement of a distal finger or toe may appear as erythema which should not be confused with the chilblains-like findings potentially associated with COVID-19 infection. We review the clinical manifestations of and explore potential therapeutic options for this uncommon, clinically striking dermatosis.
