Erytheme scarlatiniforme desquamatif recidivant ou maladie de Fereol-Besnier: une entite peu connue

The erythema scarlatiniforme desquamtivum recidivans (ESDR) is rare condition, characterized by an erythema followed by large lamellar scaling. Two variants are described, a generalized and localized one. The generalized variant initially presents with fever, flue-like symptoms followed by a widespread macular erythema rapidly evolving into large lamellar scaling, except for the head where scaling is finer. The localized form is often asymptomatic and the large lamellar scaling is limited to the palms and soles. ESDR can recur within weeks or years after the first outbreak, with the localized form being more frequent at recurrence. The aetiology remains unknown. Most authors agree on a hyperergic reaction to drugs, viral and bacterial infections. Differential diagnosis includes several conditions. The medical history and the striking presentation help in making the diagnosis.
