Frey syndrome in a patient with facial melanoma: auriculotemporal syndrome presenting with gustatory sweating following wide local excision, sentinel node biopsy, and superficial parotidectomy.

Frey syndrome is characterized by erythema, flushing, and gustatory sweating in the preauricular area. It most commonly occurs after parotid surgery. A 21-year-old man who had a wide local excision, sentinel node biopsy, and superficial parotidectomy for a right temple superficial spreading melanoma and who subsequently developed gustatory sweating in the preauricular area is described. The presentation, diagnosis, pathogenesis, and treatment options of Frey syndrome are reviewed.
