see below eczema atopic

• A multifactorial, chronically persistent or chronically recurring, inflammatory skin disease of varying acuity that belongs to the group of atopic diseases and develops as a result of complex interactions between anatomical and environmental factors.
• In the individual stages of life, the topographical and morphological manifestation of the disease varies:
  • in infancy and toddlerhood (rather) polytopic, mostly localized on the extensor side, depending on the acuity also weeping.
  • In schoolchildren and adolescence, it occurs primarily as "flexural eczema", but can also be disseminated and generalized.

Mostly pronounced sebostasis with chronified, lichenified areas of atopic eczema. The eczema foci increasingly shift to the bending side.

Predilection sites are the face, neck and nape of the neck.

Lichenification and site-specificity increase with age. Eczema in the area of the large bends of the joints (popliteal and ulnar bends) is preferred. Furthermore, skin changes occur in the face and neck. Increasingly, disabling hand eczema also occurs.

Not uncommon are superimposed, complicative pyodermas, which dominate the clinical picture with weeping and scaly plaques.

In the 2nd year of life atopic eczema improves in 60-70% of cases.
