Case 4
A male with a history of spondylolysis who presented to allergy clinic at age 16 as a referral from his pediatrician for intermittent urticarial rash and an allergic reaction to lemon. The reaction had occurred the year prior and was following consumption of a lemonade Capri SunĀ®. He experienced itching of the throat and some difficulty swallowing within 20 minutes of drinking the beverage. The symptoms resolved spontaneously within an hour. He had previously tolerated lemon and lemon-flavored drinks, but had been avoiding all forms of lemon since the reaction. His physical exam at that time was unremarkable. Food skin prick testing was performed to lemon and was negative. Unfortunately, this patient could not be reached for further mold testing.
