[Lymphoedema after an adder bite].

Bites from the adder, Vipera berus, are well known for causing local and general toxicity. We report a case of a 63-year-old female who was bitten in one of her lower extremities. She was seen twice in the emergency department with symptoms and signs consistent with severe envenomation. Despite treatment with antihistamines and corticosteroids the oedema persisted. A lymphoscintigraphy was performed showing dermal backflow in the right leg, confirming the diagnosis of lymphoedema. Based on the present case report and review of the literature antivenom therapy should be considered more actively.
