Acute inflammatory edema
The proposed pathogenesis of AIE is that acute volume overload in the setting of impaired lymphatic drainage leads to the accumulation of dermal edema. This, in turn, is thought to cause microtrauma to the connective tissue in affected areas, with subsequent influx of inflammatory mediators.
AIE differs from cellulitis in that it is nontender.
