Anaphylaxis Presenting as Uvulitis

The authors present a case of a young man who woke up with uvular swelling resulting in a severely narrowed airway. He had ingested peanut butter the prior night but was unaware of any allergies. He was treated with epinephrine, diphenhydramine, and methylprednisolone which resulted in resolution of the airway compromise. The authors discuss the mechanism of anaphylaxis and the emergency management of this life-threatening condition.
