Skin testing is the diagnostic cornerstone for allergies and is considered extremely safe. It is usually performed with the prick and the prick-to-prick method. The aim of this study is to report the first two pediatric cases of systemic allergic reactions during skin prick tests (SPT) with commercial food allergens. Both patients had a history of fish allergy. A 5-year-old girl, with a history of atopic dermatitis and asthma, reported an episode of urticaria and angioedema due to ingestion of fish, which had occurred 2 years before consultation. Ten minutes after having completed SPT to fish extracts, which had resulted positive, she suffered from generalized pruritus, nausea, stomach pain, and loss of consciousness. A 9-year-old boy, with a history of asthma and two episodes of acute urticaria and angioedema upon eating fish during infancy, reported a recent episode of oropharyngeal pruritus after tasting salmon. He was evaluated for fish allergy with SPT but developed conjunctivitis and acute urticaria during the first 10 min of the test. Anaphylaxis appears to be a rare side effect of skin testing in pediatric patients. Children with a history of asthma and atopic dermatitis are more likely to react.
