Brown recluse spider bite to the upper lip
Abstract:
Brown recluse spiders are predominantly found in south central United States. Their bites usually cause mild self-limiting reactions, although localized tissue necrosis and rare systemic, potentially fatal, envenomations are known to occur. Herein, we report an atypical presentation of a brown recluse bite in a 20 year old female who was admitted to the intensive care unit due to angioedema and cellulitis. We photographically document the bite site for twenty-four hours following envenomation. She received glucocorticoids, antihistamines, antibiotics and dapsone while hospitalized and was subsequently discharged with complete resolution of symptoms without the development of tissue necrosis or scarring.
