Cutaneous findings leading to a diagnosis of superior vena cava syndrome: A case report and review of the literature.

Superior vena cava syndrome, which occurs in approximately 15,000 persons in the United States annually, consists of a collection of symptoms and signs resulting from the obstruction of the superior vena cava (SVC). An early and prominent symptom of this condition is a constellation of superficial, dilated, vertically oriented and tortuous cutaneous venules or veins above the ribcage margins, often presenting as a blanchable violaceous eruption. Herein, we report a case of superior vena cava syndrome diagnosed in our dermatology clinic.
