Background: Allergic urticaria is one of commonest skin disorders that can be met in clinical practice. It can be classified as acute or chronic based on symptoms duration. It might be associated with allergic angioedema as well. Methods: In this study 202 patients with urticaria from the out-patient clinic of rheumatology and dermatology in Menoufia university hospital and pediatric allergy unit, Ain Shams university hospital.

Results: We enrolled 131 patients with acute urticaria (97 adult and 34 pediatric) with 66.4% female and 40.5% had associated allergic angiedema. There were additional 71 patients with chronic urticaria (50 adults and 21 children) with 78.9% female. There was no significant statistical difference between acute and chronic urticaria as regard age, sex, associated allergies, family history of allergy, but there was significant statistical difference between acute and chronic urticaria as regard triggers.
