A Case of Frey's Syndrome / 대한피부과학회지

ABSTRACT

Freys syndrome is a type of pathologic gustatory hyperhidrosis occurring as a result of injury to the nerves in the region of the parotid gland. The syndrome usually manifests as unilateral flushing, sweating, and rarely pain in response to gustatory stimuli. The most likely mechanism is aberrant reinnervation of the sweat glands of the face by the severed parotid parasympathetic nerve fibers. We report a case of Freys syndrome in a 58-year-old woman who had been treated with incision and drainage at age 10 due to an abscess occurred in the parotid area. Thereafter she complained local flushing and sweating on the left infraauricular area during mastication. She was treated with 0.5% atropine cream once a day for two weeks, resulting in marked reduction of flushing and sweating proved by Minors starch-iodine test.
