Summary
Pancake syndrome or anaphylaxis after mite ingestion, known as “OMA” (Oral Mite Anaphylaxis), is a rare condition characterized by an immunoglobulin E-mediated reaction, usually severe, after consumption of mite-contaminated flours. Its prevalence is unknown, but it has been associated with different families of mites and foods such as flours, cereals, seeds, tea leaves, and sausages. Symptoms, of rapid or immediate onset, can range from urticaria, bronchospasm to anaphylaxis. Cases of exercise-induced OMA have also been reported. The first reported case of anaphylaxis due to mite ingestion was in 1993 due to consumption of a flour preparation for making beignets (fried dough). The commercial mixture under the microscope revealed the presence of Dermatophagoides farinae.
