Description
Summary:Although potatoes represent a large part of diets worldwide, adverse reactions to them are considered uncommon and usually result from ingestion, mainly in children. In contrast, immediate reactions to contact with raw potato has been reported more frequently in adults, usually in the form of an oral contact dermatitis or contact urticaria, but also may manifest as asthma, rhinoconjunctivitis, wheezing or even anaphylaxis. We report a case of non-occupational allergic contact urticaria caused by raw potato, which we then documented by prick testing.
