Except lymphedema and pretibial myxedema

All edemas are pitting edemas except lymphedema and pretibial myxedema.

All edemas are simply due to accumulation of fluid in the extracellular space and this fluid can be indented (pitting). Anaphylaxis and angioedema is no different, the release of mast cells products specially bradykinin cause vasodilation which leads to fluid accumulation in the interstitium.
