Frey syndrome

Frey syndrome is an autonomic disorder that mostly affects the face and upper chest area. It is characterized by excessive sweating and sometimes facial flushing in areas such as the forehead, upper lip, and around the mouth. This condition typically occurs in response to eating or other gustatory stimuli. The syndrome is often connected to events that involve the parotid gland, such as trauma, the presence of parotid tumors, or surgery to remove these tumors. The symptoms are usually limited to the areas served by the auriculotemporal nerve, which explains the localized nature of the sweating and flushing.

People with this condition commonly experience excessive sweating and facial flushing, particularly on the forehead, surrounding the mouth, and sometimes on the upper chest. These symptoms usually appear when eating or thinking about food.

Information about the causes of Frey syndrome is centered on situations where the parotid gland has been affected. It may develop after trauma to the parotid gland, be associated with parotid gland tumors, or occur following surgery to remove these tumors. There is no known genetic cause listed for this condition.
