Eosinophilic dermatoses

Abstract

Eosinophilic dermatoses are a heterogeneous group of diseases, characterized by an eosinophil‐rich infiltrate and/or degranulation of eosinophils. Blood eosinophilia may be an associated feature. Typical, albeit not specific histological findings include ‘flame figures’, which are caused by the accumulation of cationic proteins released by eosinophils and subsequent collagen denaturation.
