ICD-11 definition : The development of eczematous inflammation at sites distant from the primary site
of an eczema or dermatitis. The onset of such dissemination may occur days or weeks
after the primary dermatitis. The distribution of the secondary eczema tends to be
symmetrical. Venous eczema, allergic contact dermatitis, acute irritant contact dermatitis
and infective dermatitis are all potential triggers. The precise aetiopathology is
as yet poorly understood.;
