Case presentation

A 5-year-old boy presents with a history of constant scratching and complaints of itch. His mother says he gets red blotches on his skin that ‘come and go’ and that she has noticed that his nocturnal scratching has been severe enough to cause bleeding, as indicated by blood on his bed sheet in the morning. She has changed her washing powder and the child has been placed on a dairy-free and gluten-free diet, but his symptoms have not improved. The itching is distracting him at school.
