Papillary Oedema
Marked papillary oedema is often seen in Polymorphous light eruption and Sweet's syndrome but consider also Cellulitis and Erysipelas, Urticaria, Erythema multiforme Arthropod bites and some of the vesiculobullous diseases. Orf and Coxsackie virus infections can also cause a lot of papillary dermal oedema.
