Facial flushing in children: a variant of the auriculo-temporal syndrome.

Duphenix in 1757 has been credited with describing the first case of gustatory sweating which occurred after drainage of a parotid abscess. Later, Baillarger reported a case in which the sweating occurred on both sides because of bilateral parotitis. In 1923, Frey reported a case of gustatory sweating caused by an infected bullet wound of the parotid. She noted that the sweating coincided with the skin distribution of the auriculo-temporal nerve. Since her report, gustatory sweating has also been known as the "Auriculo-temporal Syndrome" or "Frey's Syndrome."
