Traumatic arteriovenous fistula of the upper lip.
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.
