Postprandial facial rash in an infant.

This article describes an infant who developed a facial rash within minutes of eating certain foods. The rash resolved within 30 minutes. The patient was diagnosed with auriculotemporal syndrome or Frey syndrome, which is characterized by sweating or flushing in the preauricular area when the patient consumes certain foods, especially those that are acidic, sour, or spicy. Because most patients outgrow the syndrome, no treatment is needed.
