:a.: an abnormal infiltration and excess accumulation of serous fluid in connective tissue or in a serous cavity —called also '''dropsy'''

:c : any of various plant [[diseases]] characterized by such swellings
==Description==
'''Edema''' (American [[English]]) or ''oedema'' (British English; both [[words]] from the [[Greek]] οἴδημα, oídēma "swelling"), formerly known as '''dropsy''' or hydropsy, is an abnormal accumulation of fluid beneath the skin or in one or more cavities of the [[body]]. Generally, the amount of [http://en.wikipedia.org/wiki/Interstitial_fluid interstitial fluid] is determined by the [[balance]] of fluid [http://en.wikipedia.org/wiki/Homeostasis homeostasis], and increased secretion of fluid into the interstitium or impaired removal of this fluid may cause edema.
==Classification==
''Cutaneous edema'' is referred to as "pitting" when, after [[pressure]] is applied to a small area, the indentation [[persists]] for some time after the release of the pressure. Peripherial pitting edema, is the more common type, results in [[water]] retention. It can be caused by systemic [[diseases]], [[pregnancy]] in some [[women]], either directly or as a result of [http://en.wikipedia.org/wiki/Heart_failure heart failure], or local conditions such as [http://en.wikipedia.org/wiki/Varicose_veins varicose veins], [http://en.wikipedia.org/wiki/Thrombophlebitis thrombophlebitis], insect bites, and [http://en.wikipedia.org/wiki/Dermatitis dermatitis].
Non-pitting edema is observed when the indentation does not persist. It is associated with such conditions as [http://en.wikipedia.org/wiki/Lymphedema lymphedema], [http://en.wikipedia.org/wiki/Lipoedema Lipoedema] and [http://en.wikipedia.org/wiki/Myxedema myxedema].[http://en.wikipedia.org/wiki/Dropsy]
