[Toxic, allergic, and inflamatory edema].
Edema is defined as the condition in which intraluminal lymph fluid components leak into the tissues and the interstitium fluid is abnormally increased. At the site of edema, toxication, allergy or inflammation occasionally occurs. This paper will focus on local skin and mucosal edema. Toxic edema is locally caused by intake of industrial goods or medical products (pharmaceuticals). Like urticaria, allergic edema is attributed to the increased vascular permeability caused by a chemical mediator. Inflammatory edema is the state in which increased inflammatory reaction in local skin causes increases in osmotic pressure of the tissues and metabolism and then inflammatory effusion accumulate there. It includes burn and cellulites.
