Titel:
Chronic relapsing urticaria confined to injection sites of upper arms.
Abstract:
New ongoing urticarial lesions confined to former injection sites of vaccination and allergy immunotherapy were observed in an 8-year-old boy. This finding can be best explained as an isotopic response phenomenon.
