Abstract

Frey’s syndrome is a neuronal dysfunction characterized by transient erythema and warmth of the face, typically unilateral, in the territory of the auriculotemporal nerve, occurring after food intake. Although it is more common in adults, it can also present in pediatric age. We describe the case of a 7-month-old infant with unilateral erythema over the temporal and mandibular regions, non-painful and non-pruritic, appearing immediately after food ingestion and resolving spontaneously within minutes. The clinical picture is consistent with Frey’s syndrome, a condition often mistaken for food allergy due to its temporal association with food introduction. Early recognition of this condition helps avoid extensive and unnecessary investigations.
