Erythema Scarlatiniforme Desquamativum Recidivans: A Rare and Puzzling Condition.

Recurrent erythema scarlatiniforme desquamativum recidivans (ESDR), also known as Féréol-Besnier disease, is a rare condition marked by a recurrent erythematous rash that is followed by extensive desquamation, primarily affecting the palms and soles. It is often preceded by prodromal symptoms such as malaise, headache, myalgias, digestive issues, and fever. The exact pathogenesis remains unknown, and diagnosis can be challenging due to its resemblance to various infectious, auto-inflammatory, or allergic conditions, leading to diagnostic variability.
