title: Traumatic arteriovenous fistula of the upper lip.
abstract: Traumatic arteriovenous fistulas can present days to years following penetrating trauma and are often challenging to diagnose and manage. Patients may present to the dermatologist with unilateral varicose veins or a pulsatile mass. Our case illustrates the value of palpation in a careful systematic approach to any new lesion, especially in the context of previous penetrating trauma. We also discuss the nomenclature of arteriovenous communications and review their current management.
