BACKGROUND: Arteriovenous malformation of the vulva is described in only a few case reports in the literature. Given the complex anatomy of the vulva, arteriovenous malformations in this location present a particularly challenging treatment dilemma.
CASE: An 11-year-old premenarchal girl with a large vulvar arteriovenous malformation was monitored for several years. After three episodes of bleeding, despite conservative management with embolization, she was taken urgently to the operating room for resection of the lesion. A multidisciplinary team participated in the 12-hour procedure. Several months after the initial surgery, the patient is without complaints and adjusting well. Labial reduction will be required once she is fully grown.
CONCLUSION: Arteriovenous malformations of the vulva require treatment before the onset of menarche because of the potential for massive hemorrhage. If first-line conservative treatment with embolization fails, a multidisciplinary team should be assembled for surgical treatment.
Arteriovenous malformations of the female genital tract are rare, congenital lesions that require a multidisciplinary approach to treatment.
