Insect Bites. A clear-fluid bulla on the legs is typical.
Stasis Dermatitis. At times, massive edema may lead to blisters and constant dripping of body fluids.

Stasis Dermatitis. Red, scaly, eczematous skin in the setting of edema. Of note, cellulitis is common on the lower legs of the older patient. But at times, stasis dermatitis is the true cause of a red rash. So if a "cellulitis" does not get better with appropriate antibiotics, consider stasis dermatitis.
Lichen Simplex Chronicus. Heavily lichenified and/or eczematous skin from itch and scratching.
Livedo Vasculopathy. (Atrophie Blanche also shown here.)
See also Ulcers, differential diagnosis.
Ankle Flare. Dilated veins from chronic venous hypertension (from venous insufficiency).
