General Discussion
** REMINDER **
The information contained in the Rare Disease Database is provided for
educational purposes only. It should not be used for diagnostic or treatment
purposes. If you wish to obtain more information about this disorder, please
contact your personal physician and/or the agencies listed in the "Resources"
section.
Frey's syndrome is characterized by flushing or sweating on one side of
the face when eating certain foods. It results from injury to the parotid
gland, a large salivary gland near the ear. Most patients tolerate the
condition, but some require treatment.
Symptoms
In Frey's Syndrome, the cheek and ear on one side of the face sweats and
becomes red whenever the patient eats hot, spicy, or very acidic food, or
chocolate. The flushed part of the face becomes less sensitive to heat. Over
time, a slightly larger area may become involved. In men, the predominant
manifestation is sweating. In women, the flushing predominates.
Causes
Frey's syndrome usually develops only after injury, surgery, or inflammation
of one of the parotid glands and the nerve supplying it. The sweating and
flushing are due to abnormal regeneration of parasympathetic nerve fibers
which have been injured, so the sweat glands and blood vessels of the skin
which normally have a sympathetic innervation acquire a parasympathetic nerve
supply. These aberrant parasympathetic nerves are stimulated when the
patient eats.
Related Disorders
Hyperhidrosis (excessive sweating) may affect the entire body or be confined
to certain areas of the body. When the entire body is affected, the eccrine
sweat glands cause the problem, while the localized type is produced by
apocrine sweat glands. When Hyperhidrosis is localized, it usually affects
the palms, soles, underarms, the area between the breasts, or the groin.
(For more information, choose "hyperhidrosis" as your search term in the Rare
Disease Database.)
Therapies: Standard
When Frey's Syndrome causes excessive discomfort, the patient should be
treated. Procaine, a local anesthetic, may be injected into the
auriculotemporal nerve supplying the area in question. Surgically, the nerve
projections near the ear and cheek may be modified. Scopolamine cream may be
applied to the affected skin.
Therapies: Investigational
The orphan drug Glycopurrolate is being developed by Robins Corporation
for patients with Frey's Syndrome.
