Acquired vulvar lymphangiectasis in a child.

A unique case of extensive acquired vulvar lymphangiectasis without lymphedema in a child is described. This lesion developed after pelvic exenteration, lymphadenectomy, and radiation therapy for rhabdomyosarcoma of the bladder. These acquired etiologic factors simulated the pathophysiology of congenital lymphangioma. She was successfully treated with surgical excision and vulvar reconstruction.
