Contact Urticaria to Raw Potato and Lentil Anaphylaxis: A Case Report.

Potatoes and lentils are highly consumed throughout the world. Adverse reactions to potatoes among children are considered uncommon and usually result from ingestion. Allergy to raw potato has mainly been described in adults, usually in the form of oral-contact dermatitis or contact urticaria, but also may manifest as asthma, rhinoconjunctivitis, wheezing, or even anaphylaxis. Lentils, chickpeas, beans, and peas are the most commonly consumed legumes in Turkey and the Mediterranean region. In the literature, type I hypersensitivity to lentils and legumes is rare. We report a case of a 16-month-old boy with both urticaria induced by raw potato and lentil-induced anaphylaxis.
