Abstract:
Oral allergy syndrome (OAS) usually presents as an immediate swelling and itching sensation of the mouth and throat after ingestion of a food allergen. OAS may be the most common food allergy-related manifestation. Watermelon and melon belong to the Cucurbitaceae family and often show allergenic cross reactivity. Profilin is a 13 kda protein that is identified as a relevant pollen allergen in airborne pollen and related plant food allergies. Profilin is found in both watermelon and melon. Here we report a case of OAS to watermelon and melon in an 11 year-old boy. He was positive to the skin prick test, patch test and oral challenge test with watermelon and melon.
