A Vulvar Venous Malformation in a 14-Year-Old Adolescent.

A vulvar venous malformation is a rare condition that can be misdiagnosed as vulvar varicose veins, but they are not the same entity. We describe the case of a 14-year-old nulliparous girl who presented with pelvic discomfort and limited ambulation secondary to a small, purple vulvar mass. The diagnosis was confirmed with the use of invasive imaging techniques after initial conservative management. Clinicians should consider venous malformations in the differential diagnosis of vulvar swelling in adolescents, and an earlier use of phlebography in patients with discordance between workup and symptoms to ensure a prompt diagnosis and decreased patient morbidity.
