Thrombotic eosinophilic vasculitis.

Eosinophilic vasculitis is characterized by pruritic erythema, papules and angio-oedema. We report a case of thrombotic eosinophilic vasculitis with leg oedema and widespread purpura, which resulted in extensive gangrene. Corticosteroids and anticoagulants relieved the symptoms; however, deep ulcers remained after the removal of gangrene. An attempt to decrease corticosteroid dose caused a recurrence of purpura. This case strongly suggests that eosinophilis evoke serious cutaneous vasculitis in the absence of hypereosinophilia.
