Urticaria
Introduction

Usually transient problem characterized by dermal edema. Chronic forms do exist, sometimes together with vasculitis.

Etiology, pathogenesis
  • hypersentitive reaction to various stimuli: alergic (IgE or complement mediated: food, drugs, insects), non-allergic (physical stimuli, like cold, vibrations, pressure) or idiopathic.
Clinical signs
  • anywhere on the skin including the lips, mucosal surfaces affected as well
  • color is white, pink or red
  • lesions can be generalized, localized, circinate, annular etc.
  • angioedema: edema of the lips and mucous membranes
  • acute attacs disappear within sevetal hours
  • chronic forms recurr
  • pruritus
  • papules, wheals, edematous plaques, angioedema
