What is erythema gyratum repens (EGR)?
Erythema gyratum repens (EGR) is a rare, extensive and rapidly migrating figurate erythema occurring as a paraneoplastic condition in most (>80%) cases. Characteristically, the concentric erythematous bands form a wood-grain appearance on the skin and the lesions may migrate quite rapidly, up to 1cm in an hour.
Blood vessels can be affected by a variety of insults, both exogenous and endogenous. When this occurs, the epidermis remains unaffected, but the skin becomes red or pink and often oedematous. This is a reactive erythema.
