Worsening of eczematous skin symptoms in atopic dermatitis under UV or sunlight exposure (especially triggered by long-wave UVA). This form is present in only a small proportion of patients with (extrinsic) atopic eczema. Photosensitive atopic eczema, however, proves to be eminently chronic and resistant to therapy.

Occurrence/Epidemiology
