    • Focal infections
    • Allergic diathesis
    • Nerve root irritation

• Primary florescence: "Seropapel", a urticarial nodule > 5 mm, sometimes with central vesicle and surrounding redness. In fact, however, the disease begins without proper primary florescence.

• First the patient states an extremely strong, stinging, punctate itching, the seropapular is scratched. As soon as blood is visible, the pruritus stops. On dermatological presentation, often only residual erosion or a crust is visible.

• Anamnesis
