Abstract
We present a 15-year-old female patient with an anaphylactic reaction to a jellyfish sting, sustained while surfing in the Mediterranean Sea. She experienced immediate difficulty in breathing, hoarseness and itching and was taken by ambulance to the emergency department, receiving intramuscular adrenaline on the way. She presented with periorbital swelling and facial edema and improved with systemic steroids and antihistamines. She was discharged 2 days later with allergy service follow up at our institution. This is the first case report documenting anaphylaxis due to Mediterranean jellyfish envenomation.
