Oral Allergy Syndrome Associated with Jicama.

Background: The occurrence of oral symptoms after food consumption defines oral allergy syndrome (OAS). Thus, our objective was to report the association of oral allergy syndrome triggered by jicama. Methods: In this study, we report 10 cases of OAS associated with jicama eating. Results: Of the total cases, 6 were women; the mean age of the group was 28.3 ± 11.4 years. All patients suffered from allergic rhinitis and 3 of them also had asthma. On average, patients experienced the onset of symptoms 5 minutes after eating jicama. As expected, the patients had oral ailments, mainly itching in the pharynx, palate, and lips; furthermore, 4 out of 10 also had skin symptoms. The skin test by the prick-prick technique with fresh jicama had a mean diameter of 8.1 ± 5.4 mm. Conclusion: In closing, jicama should be considered as a cause of OAS, especially in regions where it is cultivated and eaten in large quantities.
