[Sensitisation to 'poffertjes' as a result of sleeping on a pillow containing buckwheat].

A 19-year-old man suffered an anaphylactic reaction after eating 'poffertjes' (small Dutch pancakes). This reaction appeared to be the result of an IgE-mediated allergy to buckwheat, a principal ingredient of 'poffertjes'. It is highly likely that the patient was sensitised by sleeping on a pillow stuffed with buckwheat husk.
