[Urticarial rash in cow-milk allergy (author's transl)]

Five recent cases of urticarial rash with cow-milk allergy are reported. They all occur at the time of weaning in children who have been sucking during at least three weeks. In three of those cases, digestive manifestations were also found. The histological pattern of the skin showed a vasculitis with deposits of fibrinogen and complement. The steadily high rate of IgE and positive cow-milk RAST in five cases give arguments for reaginic allergy in extra digestive manifestations of cow-milk proteins allergy. The treatment is the suppression of cow-milk and of any products which might contain milk proteins. Our cases had a favorable evolution.
